!!!Drag reduction during oil-water pipe flows with polymeric additives
<<<
The reduction in pressure drop in single phase flows with the addition of polymeric additives (Drag Reducing Polymers, DRP) is a known phenomenon. Studies on two-phase flows, however, are limited. Our group was the first to report on the effect of polymeric additives on oil-water flows. We observed that significant changes occur on flow pattern boundaries when DRP are added in the water phase as waves in stratified wavy flow become smoother. Pressure drop is also significantly reduced sometimes up to 40% compared to flow without polymers.
Some of the drag reduction phenomena can be observed as follows (a) Flow without DRP (b) Flow with DRP:
*Stratified Smooth Flow

*Stratified Wavy Flow

*Dual Continuous Flow

*Slug Flow

!!!Effect of Taylor bubble flow characteristics on mass transfer and reaction rates in microchannel reactors.
<<<
In Taylor gas-liquid flow pattern, liquid slugs are alternating with gas bubbles, with equivalent spherical diameters larger than the flow channel size. A liquid film surrounds the bubbles and separates them from the channel wall. Within the liquid slugs, circulation takes place which ensures very good mixing while the separation of the bulk liquid with the bubbles significantly reduces axial mixing in the liquid. The combination of good radial mass transfer and low-axial mass transfer in the liquid makes Taylor flow suitable for two-phase applications, that involve mass transfer or single-phase liquid applications which suffer from large back-mixing. This type of flow pattern appears in some common systems, namely, blood flow in capillary vessels, polymer blow moulding, flow of foams through porous media.
[img[taylor.jpg]]
The sizes of the Taylor bubbles and the liquid slugs affect mass transfer. Unlike large scale flows, these sizes are mainly defined by the conditions at the inlet. We are investigating the bubble and slug sizes formed at inlets of different geometries both experimentally and numerically using Computational Fluid Dynamics (CFD) simulations.
Despite its good mass transfer characteristics, mass transfer limitations can appear even during Taylor flow in case of fast reactions. We are currently studying different ways of improving mass transfer characteristics in Taylor flow including reduction of channel size and use of non-straight channel geometries.

|Description|select and extract tiddlers from your ~TiddlyWiki documents and save them to a local file|
When many people edit copies of the same TiddlyWiki document, the ability to easily copy and share these changes so they can then be redistributed to the entire group is very important. This ability is also very useful when moving your own tiddlers from document to document (e.g., when upgrading to the latest version of TiddlyWiki, or 'pre-loading' your favorite stylesheets into a new 'empty' TiddlyWiki document.)
ExportTiddlersPlugin let you ''select and extract tiddlers from your ~TiddlyWiki documents and save them to a local file'' or a remote server (requires installation of compatible server-side scripting, still under development...). An interactive control panel lets you specify a destination, and then select which tiddlers to export. A convenient 'selection filter' helps you pick desired tiddlers by specifying a combination of modification dates, tags, or tiddler text to be matched or excluded. ''Tiddler data can be output as ~TiddlyWiki "storeArea ~DIVs" that can be imported into another ~TiddlyWiki or as ~RSS-compatible XML that can be published for RSS syndication.''
!!!!!Inline interface (live)
<<<
<<exportTiddlers inline>>
<<<
!!!!!Usage
<<<
Optional "special tiddlers" used by this plugin:
* SiteUrl^^
URL for official server-published version of document being viewed (used in XML export)
default: //none//^^
* SiteHost^^
host name/address for remote server (e.g., "www.server.com" or "192.168.1.27")
default: //none//^^
* SitePost^^
remote path/filename for submitting changes (e.g., "/cgi-bin/submit.cgi")
default: //none//^^
* SiteParams^^
arguments (if any) for server-side receiving script
default: //none//^^
* SiteNotify^^
addresses (if any) for sending automatic server-side email notices
default: //none//^^
* SiteID^^
username or other authorization identifier for login-controlled access to remote server
default: current TiddlyWiki username (e.g., "YourName")^^
* SiteDate^^
stored date/time stamp for most recent published version of document
default: current document.modified value (i.e., the 'file date')^^
<<<
!!!!!Example
<<<
<<exportTiddlers>>
<<<
!!!!!Installation
<<<
Import (or copy/paste) the following tiddlers into your document:
''ExportTiddlersPlugin'' (tagged with <<tag systemConfig>>)
create/edit ''SideBarOptions'': (sidebar menu items)
^^Add {{{<<exportTiddlers>>}}} macro^^
<<<
!!!!!Revision History
<<<
''2007.04.19 [2.3.0]'' in exportData(), pass SiteURL value as param to saveToRss(). Fixes 'undefined' appearing in tiddler link in XML output. Also, in refreshExportList(), added 'sort by tags'. Also, added 'group select'... selecting a heading (date,author,tag) auto-selects all tiddlers in that group.
''2007.03.02 [2.2.6]'' in onClickExportButton(), when selecting open tiddlers for TW2.2, look for "storyDisplay" instead of "tiddlerDisplay" but keep fallback to "tiddlerDisplay" for TW2.1 or earlier
''2007.03.01 [2.2.5]'' removed hijack of store.saveChanges() (was catching save on http:, but there are other solutions that do a much better job of handling save to server.
|please see [[ExportTiddlersPluginHistory]] for additional revision details|
''2005.10.09 [0.0.0]'' development started

!!!Pilot scale rig
<<<
The test pipe consists of two 8.0 meter sections of 38mm ID tube connected by a U-turn. Each section is made up of 1m and 2m pipes joined with appropriate units to give crevice-free connections. This configuration allows instrumentation to be placed between the connectors at any location along the test pipe. Test pipes made both from acrylic and stainless steel are used. In the steel pipe, two 54cm transparent acrylic pipes are installed for the observation of flow development.
* Large experimental rig
[img[largerig.jpg]]
<<<
!!!Small scale rig
<<<
The test section consists of a 3.6 m long acrylic pipe with 14 mm ID. The mixture returns via a PVC pipe to a gravity settler. The test section is made up of shorter acrylic pipes joined with appropriate units that allow instrumentation to be put in-between them. This configuration offers the flexibility to install the various probes at different locations along the test section.
[img[smallrig3.jpg]][img[smallrig2.jpg]]
<<<
!!!Microchannel flows
<<<
The set up consists of pumps and flowmeters. Various test sections are used fabricated from different materials (e.g. glass, acrylic, silicon). Specially fabricated separators are attached at the end of the test section to ensure smooth separation of the two phases and minimum pressure fluctuations when the phases exit the channel, particularly in the case of Taylor bubbles.

!!!Flow pattern transitions
<<<
A number of flow patterns can form during oil-water flow in pipelines. Photographs of the main ones we have observed in our facilities are given below.
*Stratified Smooth Flow
[img[ssmooth.jpg]]
*Dual Continuous Flow
[img[dualcontinuous.jpg]]
*Dispersed Flow
[img[dispersed.jpg]]
*Annular Flow
[img[annular.jpg]]
The boundaries of these patterns depend on fluid properties, pipe size and phase flow velocities. We have developed a model to predict the transition from stratified to dispersed patterns. According to the model, drops will form from the wave crests of stratified wavy flow when the waves reach certain critical characteristics. Data on the conditions for transition from stratified to dispersed patterns are used to validate the model. We also study the wave development and characteristics as the upper boundary of stratified wavy flow is approached.
<<<
!!!Phase inversion
<<<
Phase inversion in a liquid-liquid dispersion is the phenomenon where the continuous phase changes to become dispersed and the dispersed becomes continuous. It is important to be able to predict the critical volume fraction of the phases (i.e phase inversion point) where this transition occurs as phase inversion is accompanied by changes in the mixture rheology as well as drop size and interfacial area, that can affect mass transfer processes.
Our investigations in phase inversion are both experimental and theoretical. We conduct controlled experiments to study the change in oil-water rheology, phase distribution and drop size distribution before and after phase inversion from a variety of fluid properties, pipe diameters and pipe-wall properties. Our aim is to establish a mechanism for phase inversion in immiscible liquid-liquid flows. Mechanisms based on energy minimization and on rates of droplet break up and coalescence are considered. To aid this, we have developed a population balance model to predict the evolution of drop size distribution as the dispersed phase fraction increases and the system approaches phase inversion.
<<<
In collaboration with the [[Chemical Reaction Engineering group|http://www.ucl.ac.uk/chemeng]], we investigate the characteristics of gas-liquid flows in microchannels and their interaction with mass transfer and reaction processes. Microreactors allow increased rates of heat/mass transfer due to very thin fluid layers involved and offer the potential of process intensification. Understanding the effect of microscale on fluid dynamics and transport phenomena is necessary for better design and operation of these systems.
!!!Flow patterns during gas-liquid flow in microchannels
<<<
The enhanced surface area to volume ratio at microsystems increases the importance of surface/ interfacial forces (which are usually negligible in large scale processes) while it decreases the influence of volume forces such as gravity. Flow patterns in multiphase systems will therefore be greatly affected by interfacial forces and differ significantly from what is expected in macroscale. We investigate the characteristics of flow patterns formed and their transitions during gas-liquid flow in microchannels with different geometries and channel wall properties.

Our research group also hosts visiting researchers and affiliate students from across the world. Many undergraduates and ~MSc students have also chosen to conduct their research project within our group.
Research in the Multiphase Flow group focuses on establishing the fundamental understanding in hydrodynamics for processes that involve flow of two fluid phases (liquid-liquid or gas-liquid). Our experimental and modeling approach aims at describing the phenomena and applying them in industrial practice. We investigate flows ranging from large channels to microchannels.
Large scale investigations focus on the flow of oil-water mixtures in horizontal and inclined pipelines, relevant to the petroleum industry. We also study fundamental phenomena, such as rheology of dispersions and phase inversion, that are of interest not only to the petroleum processes but also to a large number of other processes involving liquid-liquid dispersions such as extraction and emulsification.
In microchannels, the flow characteristics of gas-liquid mixtures are studied. Taylor bubble flow is the main research interest among possible patterns.
We have developed and constantly upgrade state of the art facilities and instrumentation, which are mainly built in house, for the observation and measurement of a variety of flow properties. These have facilitated tackling some of the most challenging issues on multiphase flow phenomena.

The application of the impedance probe has been extended to measuring in-situ velocity and drop size when it is used in conjunction with a second probe. This is called the dual impedance probe.

|Description|interactive controls for import/export with filtering.|
When many people share and edit copies of the same TiddlyWiki document, the ability to quickly collect all these changes back into a single, updated document that can then be redistributed to the entire group is very important. It can also be very extremely helpful when moving your own tiddlers from document to document (e.g., when upgrading to the latest version of TiddlyWiki, or 'pre-loading' your favorite stylesheets into a new 'empty' TiddlyWiki document.)
This plugin lets you selectively combine tiddlers from any two TiddlyWiki documents. An interactive control panel lets you pick a document to import from, and then select which tiddlers to import, with prompting for skip, rename, merge or replace actions when importing tiddlers that match existing titles. Automatically add tags to imported tiddlers so they are easy to find later on. Generates a detailed report of import 'history' in ImportedTiddlers.
!!!!!Usage
<<<
{{{<<importTiddlers>>}}} or {{{<<importTiddlers core>>}}}
invokes the built-in importTiddlers macro (TW2.1.x+). If installed in documents using TW2.0.x or earlier, fallback is to use 'link' display (see below)
{{{<<importTiddlers link label tooltip>>}}}
The ''link'' keyword creates an "import tiddlers" link that when clicked to show/hide import control panel. ''label'' and ''tooltip'' are optional text parameters (enclosed in quotes or {{{[[...]]}}}, and allow you to override the default display text for the link and the mouseover help text, respectively.
{{{<<importTiddlers inline>>}}}
creates import control panel directly in tiddler content
<<importTiddlers inline>>
Press ''[browse]'' to select a TiddlyWiki document file to import, and then press ''[open]''. Alternatively, you can type in the path/filename or a remote document URL (starting with http://). When you have entered the desired source location, press ''[load]'' to retrieve the tiddlers from the remote source. //Note: There may be some delay to permit the browser time to access and load the document before updating the listbox with the titles of all tiddlers that are available to be imported.//
Select one or more titles from the listbox (hold CTRL or SHIFT while clicking to add/remove the highlight from individual list items). You can press ''[select all]'' to quickly highlight all tiddler titles in the list. Use the ''[-]'', ''[+]'', or ''[=]'' links to adjust the listbox size so you can view more (or less) tiddler titles at one time. When you have chosen the tiddlers you want to import and entered any extra tags, press ''[import]'' to begin copying them to the current TiddlyWiki document.
''select: all, new, changes, or differences''
You can click on ''all'', ''new'', ''changes'', or ''differences'' to automatically select a subset of tiddlers from the list. This makes it very quick and easy to find and import just the updated tiddlers you are interested in:
>''"all"'' selects ALL tiddlers from the import source document, even if they have not been changed.
>''"new"'' selects only tiddlers that are found in the import source document, but do not yet exist in the destination document
>''"changes"'' selects only tiddlers that exist in both documents but that are newer in the source document
>''"differences"'' selects all new and existing tiddlers that are different from the destination document (even if destination tiddler is newer)
''Import Tagging:''
Tiddlers that have been imported can be automatically tagged, so they will be easier to find later on, after they have been added to your document. New tags are entered into the "add tags" input field, and then //added// to the existing tags for each tiddler as it is imported.
''Skip, Rename, Merge, or Replace:''
When importing a tiddler whose title is identical to one that already exists, the import process pauses and the tiddler title is displayed in an input field, along with four push buttons: ''[skip]'', ''[rename]'', ''[merge]'' and ''[replace]''.
To bypass importing this tiddler, press ''[skip]''. To import the tiddler with a different name (so that both the tiddlers will exist when the import is done), enter a new title in the input field and then press ''[rename]''. Press ''[merge]'' to combine the content from both tiddlers into a single tiddler. Press ''[replace]'' to overwrite the existing tiddler with the imported one, discarding the previous tiddler content.
//Note: if both the title ''and'' modification date/////time match, the imported tiddler is assumed to be identical to the existing one, and will be automatically skipped (i.e., not imported) without asking.//
''Import Report History''
When tiddlers are imported, a report is generated into ImportedTiddlers, indicating when the latest import was performed, the number of tiddlers successfully imported, from what location, and by whom. It also includes a list with the title, date and author of each tiddler that was imported.
When the import process is completed, the ImportedTiddlers report is automatically displayed for your review. If more tiddlers are subsequently imported, a new report is //added// to ImportedTiddlers, above the previous report (i.e., at the top of the tiddler), so that a reverse-chronological history of imports is maintained.
If a cumulative record is not desired, the ImportedTiddlers report may be deleted at any time. A new ImportedTiddlers report will be created the next time tiddlers are imported.
Note: You can prevent the ImportedTiddlers report from being generated for any given import activity by clearing the "create a report" checkbox before beginning the import processing.
<<<
!!!!!Installation
<<<
copy/paste the following tiddlers into your document:
''ImportTiddlersPlugin''
''ImportTiddlersPluginPatch2.1.x'' (only for installation in TW2.1.x or earlier)
(both tagged with <<tag systemConfig>>)
>Important Notes:
>* As of 6/27/2007, "patch" functions that provide backward-compatibility with TW2.1.x and earlier have been split into a separate [[ImportTiddlersPluginPatch2.1.x]] tiddler to reduce installation overhead for //this// plugin. You only need to install this additional plugin tiddler when using ImportTiddlersPlugin in documents using TW2.1.x or earlier.
>* As of 3/21/2007, the interactive {{{<<importTiddlers>>}}} and non-interactive {{{<<loadTiddlers>>}}} macro definitions and related code have been split into separate [[ImportTiddlersPlugin]] and [[LoadTiddlersPlugin]] to permit selective installation of either the interactive and/or non-interactive macro functions
''Quick Installation Tip #1:''
If you are using an unmodified version of TiddlyWiki (core release version <<version>>), you can get a new, empty TiddlyWiki with the Import Tiddlers plugin pre-installed (''[[download from here|TW+ImportExport.html]]''), and then simply import all your content from your old document into this new, empty document.
<<<
!!!!!Revision History
<<<
''2007.06.27 [3.5.5]'' added missing 'fields' params to saveTiddler() calls. Fixes problem where importing tiddlers would lose the custom fields. Also, moved functions for backward-compatibility with TW2.1.x to separate [[ImportTiddlersPluginPatch2.1.x]] tiddler, reducing the size of //this// plugin tiddler by a significant amount.
''2007.06.25 [3.5.4]'' added calls to store.suspendNotifications() and store.resumeNotifications(). Eliminates redisplay processing overhead DURING import activities
|please see [[ImportTiddlersPluginHistory]] for additional revision details|

Different instruments are used to measure the following flow properties.
*''Pressure Gradient''
Pressure gradient is measured with differential pressure transducers. An inclined inverse water manometer is used at the lowest phase flow rates. Both these devices are attached to the experimental facilities via pressure tapping lines which are connected to the pipe using special couplings.
*''In-situ composition (Hold Up)''
Average in-situ composition (hold up) of the flow is mainly measured using [[quick closing valves (QCV)|Quick Closing Valves (QCV)]]. The method is simple and involves simultaneously stopping the flow and isolating a known volume of mixture between two valves placed at either end of a pipe section. The mixture is then removed into a measuring cylinder via a valve.
*''Local Flow Parameters''
These are measured with local probes. All probes are mounted on short sections of pipe that can be inserted between any two lengths of the test sections.
''Phase continuity'' at a location in the pipe and phase inversion are detected using conductivity probes. We employ two configurations. The first consists of two wires ([[conductivity probe|Conductivity Probe]]) inserted into the pipe in line with the direction of flow at a distance of 10mm apart. A water continuous flow will conduct electricity and therefore give a signal, and vice versa for an oil continuous flow. In the second configuration a pair of metal rings is mounted flush with the pipe wall (ring probe). When the phase wetting the wall is water there will be a signal from the two probes, while there will be no signal if oil wets the wall.
''Phase distribution'' at a point in a pipe cross section can be measured using a high frequency [[impedance probe|Impedance Probe]], which uses the differences in the electrical properties of the two fluids. It is capable of sampling at frequencies up to 90kHz. From sampling at different locations in the pipe cross section and integrating the results produces in situ [[phase distribution diagrams|Phase Distribution Diagram]].
*''Drop Size Distribution''
Drop size distribution at a point in the pipe cross section can be obtained with two impedance probes located a certain distance apart in line with the flow (a similar configuration to the conductivity probe). By cross-correlating the signals from the two probes, and knowing their separation distance, local drop velocity can be calculated. An extension of this is the measurement of drop chord lengths detected by the probes, by combining the velocity of the drops with the time a drop was present at either impedance probe. Chord lengths can then be transformed to diameter distributions using various statistical methods.
*''Turbulence Measurements''
We use a [[hot film CTA anemometer|Hot Film CTA Anemometer]] by Dantec (90N10/90C10) to obtain velocity profiles and turbulence intensity in our two phase flows. The anemometer probe is used in combination with a Pitot tube for calibration and a thermometer for measuring the mixture temperature close to the probe, required for correct interpretation of the hot film signal.
*''Wave Characteristics''
We use a [[conductivity wire probe|Conductivity Wire Probe]] to measure the instantaneous height of the interface in stratified flows and obtain wave characteristics such as length and amplitude. The probe consists of two conducting wires that are at a certain distance apart and stretched across a vertical pipe diameter.
*''Contact Angle/Surface Tension''

|Description|macro for automated updates or one-click installations of tiddlers from remote sources|
!!!!!Usage
<<<
Syntax:
{{{<<loadTiddlers label:text prompt:text filter source quiet confirm force noreport tag tag tag...>>}}}
Example:
{{{<<loadTiddlers "label:load tiddlers from %0" example.html confirm temporary>>}}}
<<loadTiddlers "label:load tiddlers from %0" example.html confirm temporary>>
Where:
''"""label:text"""'' and ''"""prompt:text"""''
>defines link text and tooltip (prompt) that can be clicked to trigger the load tiddler processing. If a label is NOT provided, then no link is created and the loadTiddlers function is performed whenever the containing tiddler is rendered.
''filter'' (optional) determines which tiddlers will be automatically selected for importing. Use one of the following keywords:
>''"all"'' retrieves ALL tiddlers from the import source document, even if they have not been changed.
>''"new"'' retrieves only tiddlers that are found in the import source document, but do not yet exist in the destination document
>''"changes"'' retrieves only tiddlers that exist in both documents for which the import source tiddler is newer than the existing tiddler
>''"updates"'' retrieves both ''new'' and ''changed'' tiddlers (this is the default action when none is specified)
>''""""tiddler:TiddlerName""""'' retrieves only the specific tiddler named in the parameter.
>''""""tag:text""""'' retrieves only the tiddlers tagged with the indicated text.
>> Note: ''if an existing tiddler is tagged with 'noReload', then it will not be overwritten'', even if the inbound tiddler has been selected by the filtering process. This allows you to make local changes to imported tiddlers while ensuring that those changes won't be lost due to automatic tiddler updates retrieved from the import source document.
''source'' (required) is the location of the imported document. It can be either a local document path/filename in whatever format your system requires, or a remote web location (starting with "http://" or "https://")
>use the keyword ''ask'' to prompt for a source location whenever the macro is invoked
''"quiet"'' (optional)
>supresses all status message during the import processing (e.g., "opening local file...", "found NN tiddlers..." etc). Note that if ANY tiddlers are actualy imported, a final information message will still be displayed (along with the ImportedTiddlers report), even when 'quiet' is specified. This ensures that changes to your document cannot occur without any visible indication at all.
''"confirm"'' (optional)
>adds interactive confirmation. A browser message box (OK/Cancel) is displayed for each tiddler that will be imported, so that you can manually bypass any tiddlers that you do not want to import.
''"force"'' (optional)
>import all matching tiddlers, even if unchanged
''"noreport"'' (optional)
>suppress generation of [[ImportedTiddlers]] report
''"tag tag tag..."'' (optional)
>any remaining parameters are used as tag values to be added to each imported tiddler (i.e., "tag-on-import")

!!!!!Revision History
<<<
''2007.06.27 [3.4.8]'' added missing 'fields' params to saveTiddler() call. Fixes problem where importing tiddlers would lose the custom fields.
''2007.06.25 [3.4.7]'' add calls to store.suspendNotifications() and store.resumeNotifications() to eliminate redisplay overhead DURING import activities.
''2007.05.27 [3.4.6]'' in handler(), loadRemoteFile() and doImport(), added 'noreport' flag to suppress generation of ImportedTiddlers
''2007.05.27 [3.4.5]'' in handler(), initialize 'newTags' to [] (empty array) instead of null... fixes fatal error when loading tiddler without autotagging.
''2007.04.22 [3.4.4]'' in readTiddlersFromHTML(), for TW2.2 and above, use importTiddlyWiki() (new core functionality) to get tiddlers from remote file content. Also, copied updated TW21Loader.prototype.internalizeTiddler() definition from TW2.2b5 so plugin can read tiddlers from TW2.2+ even when running under TW2.1.x
''2007.04.05 [3.4.3]'' in doImport(), changed this.readTiddlersFromHTML(html) to config.macros.loadTiddlers.readTiddlersFromHTML(html). Fixes error caused when ImportTiddlersPlugin has NOT been installed along side this plugin.
''2007.03.26 [3.4.2]'' renamed import() to doImport() to fix IE load-time error ("identifier expected"). This may also cause a problem with FF1.5.0.x.... Apparently, "import" is a reserved word in some browsers...
''2007.03.22 [3.4.1]'' code cleanup: moved all functions inside object def'n, re-wrote report function
''2007.03.21 [3.4.0]'' split ImportTiddlersPlugin and LoadTiddlersPlugin functionality into separate plugins

|Description|backward-compatible function patches for use with LoadTiddlersPlugin and TW2.1.x or earlier|
!!!!!Usage
<<<
The current version LoadTiddlersPlugin is compatible with the TW2.2.x core functions.
This "patch" plugin provides additional functions needed to enable the current version of LoadTiddlersPlugin to operate correctly under TW2.1.x or earlier.
{{medium{You do not need to install this plugin if you are using TW2.2.0 or above}}}
(though it won't hurt anything if you do... it will just take up more space).
<<<

|Description|Quickly create new TiddlyWiki documents from your existing document, with just one click|
Use the {{{<<newDocument>>}}} macro to place a "new document" link into your sidebar/mainmenu/any tiddler (wherever you like). Select this command to automatically create a "new.html" document containing a specific set of tagged tiddlers. Optional parameters let you specify an alternate path/filename for the new file, or different tags to match. You can also indicate "ask" for either parameter, which will trigger a prompt for input when the command is selected.
!!!!!Usage
<<<
{{{<<newDocument label:text prompt:text filename tag tag tag...>>}}}
{{{<<newDocument label:text prompt:text filename all>>}}}
{{{<<newDocument label:text prompt:text filename snap ID>>}}}
{{{<<newDocument label:text prompt:text filename snap here>>}}}
{{{<<newDocument label:text prompt:text nofile print ID>>}}}
{{{<<newDocument label:text prompt:text nofile print here>>}}}
where:
* ''label:text'' defines //optional// alternative link text (replaces default "new document" display)
* ''prompt:text'' defines //optional// alternative tooltip text for 'mouseover' prompting (replaces default hard-coded tooltip text)
* ''filename'' is any local path-and-filename. If no parameters are provided, the default is to create the file "new.html" in the current directory. If a filename is provided without a path (i.e., there is no "/" in the input), then the current directory is also assumed. Otherwise, this parameter is expected to contain the complete path and filename needed to write the file to your local hard disk. If ''ask'' is used in place of the filename parameter then, when the command link is selected, a message box will be automatically displayed so you can select/enter the path and filename.
* ''tag tag tag...'' is a list of one or more space-separated tags (use quotes or {{{[[]]}}} around tags that contain spaces). The new document will include all tiddlers that match at least one of the tags in the list. The default is to include tiddlers tagged with <<tag includeNew>>. The special value ''all'' may be used to match every tiddler (even those without tags). If ''ask'' is used in place of the tags then, when the command link is selected, a message box will be automatically displayed so you can enter the desired tags at that time.
* When you use the keyword ''snap'' in place of the tags, you can generate a file containing the //rendered// CSS-and-HTML that is currently being displayed in browser. By default, the snapshop uses the 'contentWrapper' DOM element ID to automatically include all the TiddlyWiki elements, such as the sidebars and header, in addition to the center 'story' column containing the tiddler content.
* When you use the keyword ''print'' in place of the tags, a snapshot is generated, but the contents are not written to a file. Instead, they are displayed in a separate browser tab/window, and the print dialog for that tab/window is automatically invoked.
* You can limit the snapshot to capture only a portion of the rendered TiddlyWiki elements by specifiying an optional alternate DOM element ID, such as "displayArea" (the entire center 'story' column) or even just a single tiddler (e.g., "tidderMyTiddlerTitle", assuming that "MyTiddlerTitle" is currently displayed). Only the portions of the document that are contained //within// the specified DOM element will be transcribed to the resulting snapshot file. If ''ask'' is used in place of a DOM element ID, you will be prompted to enter the ID (default is "contentWrapper") when the snapshot is being taken. This allows you to easily enter the ID of any currently displayed tiddler to make quick snapshots of specific tiddlers. If ''here'' is used in place of a DOM element ID, the current tiddler id is used.
Note: as of version 1.4.0 of this plugin, support for selecting tiddlers by using tag *expressions* has been replaced with simpler, more efficient "containsAny()" logic. To create new ~TiddlyWiki documents that contain only those tiddlers selected with advanced AND/OR/NOT Boolean expressions, you can use the filtering features provided by the ExportTiddlersPlugin (see www.TiddlyTools.com/#ExportTiddlersPlugin).
<<<
!!!!!Examples:
<<<
{{{<<newDocument>>}}}
equivalent to {{{<<newDocument new.htm includeNew systemTiddlers>>}}}
creates default "new.html" containing tiddlers tagged with either<<tag includeNew>>or<<tag systemTiddlers>>
try it: <<newDocument>>
{{{<<newDocument empty.html systemTiddlers>>}}}
creates "empty.html" containing only tiddlers tagged with<<tag systemTiddlers>>
//(reproduces old-style (pre 2.0.2) empty file)//
try it: <<newDocument empty.html systemTiddlers>>
{{{<<newDocument "label:create Import/Export starter" ask importexport>>}}}
save importexport tiddlers to a new file, prompts for path/file
try it: <<newDocument "label:create Import/Export starter" ask importexport>>
{{{<<newDocument ask ask>>}}}
prompts for path/file, prompts for tags to match
try it: <<newDocument ask ask>>
{{{<<newDocument ask all>>}}}
save all current TiddlyWiki contents to a new file, prompts for path/file
try it: <<newDocument ask all>>
{{{<<newDocument ask snap>>}}}
generates snapshot of currently displayed document, prompts for path/file
try it: <<newDocument ask snap>>
{{{<<newDocument ask snap here>>}}}
generates snapshot of this tiddler ONLY, prompts for path/file
try it: <<newDocument ask snap here>>
{{{<<newDocument ask print here>>}}}
prints a snapshot of this tiddler ONLY
try it: <<newDocument nofile print here>>
<<<
!!!!!Installation
<<<
Import (or copy/paste) the following tiddlers into your document:
''NewDocumentPlugin'' (tagged with <<tag systemConfig>>)
<<<
!!!!!Revision History
<<<
''2007.03.30 [1.7.0]'' added support for "print" param as alternative for "snap". When "print" is used, the filename is ignored and ouput is directed to another browser tab/window, where the print dialog is then automatically triggered.
''2007.03.30 [1.6.1]'' added support for "here" keyword for current tiddler elementID and "prompt:text" param for specifying tooltip text
''2007.02.12 [1.6.0]'' in onClickNewDocument(), reset HTML source 'markup'
''2006.10.23 [1.5.1]'' in onClickNewDocument(), get saved parameter value for snapID instead of using default "contentWrapper" (oops!)
''2006.10.18 [1.5.0]'' new optional param for 'snap'... specify alternative DOM element ID (default is still "contentWrapper"). Based on a suggestion from Xavier Verges.
''2006.08.03 [1.4.3]'' in promptForFilename(), for IE (WinXP only), added handling for UserAccounts.CommonDialog
''2006.07.29 [1.4.2]'' in onClickNewDocument(), okmsg display is now linked to newly created file
''2006.07.24 [1.4.1]'' in promptForFilename(), check for nsIFilePicker.returnCancel to allow nsIFilePicker.returnOK **OR** nsIFilePicker.returnReplace to be processed.
''2006.05.23 [1.4.0]'' due to very poor performance, support for tag *expressions* has been removed, in favor of a simpler "containsAny()" scan for tags.
''2006.04.09 [1.3.6]'' in onClickNewDocument, added call to convertUnicodeToUTF8() to better handle international characters.
''2006.03.15 [1.3.5]'' added nsIFilePicker() handler for selecting filename in moz-based browsers. IE and other non-moz browsers still use simple prompt() dialog
''2006.03.15 [1.3.0]'' added "label:text" param for custom link text. added special "all" filter parameter for "save as..." handling (writes all tiddlers to output file)
''2006.03.09 [1.2.0]'' added special "snap" filter parameter to generate and write "snapshot" files containing static HTML+CSS for currently rendered document.
''2006.02.24 [1.1.2]'' Fix incompatiblity with TW 2.0.5 by removing custom definition of getLocalPath() (which is now part of TW core)
''2006.02.03 [1.1.1]'' concatentate 'extra' params so that tag expressions don't have to be quoted. moved all text to 'formatted' string definitions for easier translation.
''2006.02.03 [1.1.0]'' added support for tag EXPRESSIONS. plus improved documentation and code cleanup
''2006.02.03 [1.0.0]'' Created.

1) Phase distribution for 2m/s 50% input oil fraction in horizontal flow. 2) Phase distribution for 2m/s 50% input oil fraction. 5° upward inclination.
Phase Inversion defines the inversion of the dispersed phase to become continuous and vice versa. This phenomenon has been widely shown to occur within an ambivalent region. An Hysteresis effect is shown depending on the prior continuous phase before inversion. Our group investigates on the process through various parameters including pressure gradient and conductivity probes. We are also in an ongoing process to explore new technology to accurately account for the flow condition at the instant of phase inversion.

|Description|extend 'save changes' to get remote document contents and save to local filesystem |
|Status| ALPHA EXPERIMENTAL - USE AT YOUR OWN RISK |
Normally, when you are viewing a TiddlyWiki document over the web (i.e., not via {{{file://}}}) and you select the "save changes" (or "save to disk") command, an error message is displayed: //__"You need to save this TiddlyWiki to a file before you can save changes."__// This plugin extends the use of {{{<<saveChanges>>}}} so that when you are viewing and/or editing a remote TiddlyWiki document, instead of receiving this somewhat confusing and unhelpful message, you can still click the "save changes" (or "save to disk") command to ''store a copy of the remote document directly onto your local filesystem'', //including any unsaved tiddler changes/additions you have made while working on-line.//
!!!!!Usage
<<<
The plugin retrieves the TiddlyWiki source file directly from the remote server (using XMLHttpRequest) and then merges it with the tiddler content in the currently loaded document. You are then prompted for a destination path/file, and a new TiddlyWiki document file is written to the indicated location on your local file system.
''__Security in FireFox (and other browsers)__''
''FireFox needs security permissions to be set to allow a remote URL to save a new file to your local filesystem.'' Certain JavaScript features, such as reading/writing to the local filesystem, require expanded "cross-domain" privileges, normally restricted for use with ''signed'' scripts, which you can set FireFox to allow or disallow, based on the digital signature of the originator (or ''principal'') of each signed script.
However, ''unsigned'' scripts, such as TiddlyWiki, do not contain a digital signature and are not normally allowed access to filesystem functions. Fortunately, an //''unsigned''// script can still be granted expanded filesystem privileges through use of a ''codebase principal'', which relies upon the originating URL of the script (it's "codebase") to identify the "trusted source", rather than verifying a digital signature of a certificate.
>''In FireFox (and most other browsers) use of codebase principals is disabled by default'';
>To use codebase principals, go to "about:config" in your browser, and set:
>{{{signed.applets.codebase_principal_support}}} to {{{true}}}
>//note: you can also set this value by editing FireFox's {{{prefs.js}}} and adding://
>{{{user_pref("signed.applets.codebase_principal_support", true);}}}
After you have enabled codebase principals, you will begin receiving security notices whenever TiddlyWiki requests permission to invoke various privileged functions. You can press the "allow" button to permit the processing to continue, or press "deny" to prevent the privileged functions from being used by that remote site.
When you invoke {{{<<saveChanges>>}}}, there may be several of these notices in a row (perhaps as many as 10 or so) before the file saving process is done. These messages are normal, and you should ALLOW each of them, so that the file saving procedure can continue to completion. Once you are confident that the remote site is trustworthy, you can mark the "remember this decision" checkbox to eliminate additional notices for that remote site, so that the process can proceed without further interruptions. This setting will only be applied to the specific web domain in question, so you will still receive security notices when using privileged functions from any other web sites.
//Note: If codebase principals are enabled, security notices are also reported when accessing TiddlyWiki documents locally (i.e., via {{{file://}}}). This is a result of TiddlyWiki's normal file I/O processing and should always be considered safe to allow, inasmuch as you control the contents of your own local filesystem, and thus, should be able to consider the {{{file://}}} codebase location as a trusted source.//

|Description|Display tiddlers one at a time with automatic update of URL (permalink). Also, options to always open tiddlers at top/bottom of page|
Normally, as you click on the links in TiddlyWiki, more and more tiddlers are displayed on the page. The order of this tiddler display depends upon when and where you have clicked. Some people like this non-linear method of reading the document, while others have reported that when many tiddlers have been opened, it can get somewhat confusing.
!!!!!Usage
<<<
SinglePageMode allows you to configure TiddlyWiki to navigate more like a traditional multipage web site with only one item displayed at a time. When SinglePageMode is enabled, the title of the current tiddler is automatically displayed in the browser window's titlebar and the browser's location URL is updated with a 'permalink' for the current tiddler so that it is easier to create a browser 'bookmark' for the current tiddler.
Even when SinglePageMode is disabled (i.e., displaying multiple tiddlers is permitted), you can reduce the potential for confusion by enable TopOfPageMode, which forces tiddlers to always open at the top of the page instead of being displayed following the tiddler containing the link that was clicked.
<<<
!!!!!Configuration
<<<
When installed, this plugin automatically adds checkboxes in the AdvancedOptions tiddler so you can enable/disable the plugin behavior. For convenience, these checkboxes are also included here:
<<option chkSinglePageMode>> Display one tiddler at a time
<<option chkTopOfPageMode>> Always open tiddlers at the top of the page
<<option chkBottomOfPageMode>> Always open tiddlers at the bottom of the page
//(note: if both settings are selected, "top of page" is used)//
<<<
!!!!!Installation
<<<
import (or copy/paste) the following tiddlers into your document:
''SinglePageModePlugin'' (tagged with <<tag systemConfig>>)
^^documentation and javascript for SinglePageMode handling^^
When installed, this plugin automatically adds checkboxes in the ''shadow'' AdvancedOptions tiddler so you can enable/disable this behavior. However, if you have customized your AdvancedOptions, you will need to ''manually add these checkboxes to your customized tiddler.''
<<<
!!!!!Revision History
<<<
''2007.03.03 [2.3.1]'' fix typo when adding BPM option to AdvancedOptions (prevented checkbox from appearing)
''2007.03.03 [2.3.0]'' added support for BottomOfPageMode (BPM) based on request from DaveGarbutt
''2007.02.06 [2.2.3]'' in Story.prototype.displayTiddler(), use convertUnicodeToUTF8() for correct I18N string handling when creating URL hash string from tiddler title (based on bug report from BidiX)
''2007.01.08 [2.2.2]'' use apply() to invoke hijacked core functions
''2006.07.04 [2.2.1]'' in hijack for displayTiddlers(), suspend TPM as well as SPM so that DefaultTiddlers displays in the correct order.
''2006.06.01 [2.2.0]'' added chkTopOfPageMode (TPM) handling
''2006.02.04 [2.1.1]'' moved global variable declarations to config.* to avoid FireFox 1.5.0.1 crash bug when assigning to globals
''2005.12.27 [2.1.0]'' hijack displayTiddlers() so that SPM can be suspended during startup while displaying the DefaultTiddlers (or #hash list). Also, corrected initialization for undefined SPM flag to "false", so default behavior is to display multiple tiddlers
''2005.12.27 [2.0.0]'' Update for TW2.0
''2005.11.24 [1.1.2]'' When the back and forward buttons are used, the page now changes to match the URL. Based on code added by Clint Checketts
''2005.10.14 [1.1.1]'' permalink creation now calls encodeTiddlyLink() to handle tiddler titles with spaces in them
''2005.10.14 [1.1.0]'' added automatic setting of window title and location bar ('auto-permalink'). feature suggestion by David Dickens.
''2005.10.09 [1.0.1]'' combined documentation and code in a single tiddler
''2005.08.15 [1.0.0]'' Initial Release

|Description|blocks tiddlers tagged with "temporary" from being saved into the TW file|
!!!!!Usage
<<<
When the TW document is saved (either to local disk or remote URL), any tiddlers tagged with "temporary" will be skipped over, so that they are not written to the file. To keep a temporary tiddler, simply edit it and remove the tag before saving the file. This feature can be combined with various plugins that can automatically create new tiddlers, such as [[SearchOptionsPlugin]] ([[SearchResults]]) and [[ImportTiddlersPlugin]] ([[ImportedTiddlers]]) so that these transient results are not retained when you save you document.
You can also use this tag with the {{{<<loadTiddlers>>}}} macro and the //auto-tagging// features provided by [[ImportTiddlersPlugin]], so that each time you open your document, you can automatically retrieve an up-to-date set of common tiddlers that are stored in another document (either local or via remote URL), without those tiddlers being retained when you save your document.
<<<
!!!!!Configuration
<<<
When saving the document:
<<option chkTemporaryQuiet>> Suppress reporting of temporary tiddlers that have not been saved
<<option chkTemporaryKeep>> Keep temporary tiddlers (i.e., ignore the 'temporary' tag)
Enter a tag value to use when marking tiddlers as temporary: <<option txtTemporaryTag>>
<<<
!!!!!Installation
<<<
import (or copy/paste) the following tiddlers into your document:
TemporaryTiddlersPlugin
<<<
!!!!!Revision History
<<<
''2007.01.01 [1.0.0]'' initial release

!Description
UploadPlugin, with [[store.php]], provides @@upload@@ and @@save to web@@ functions. See HowToUpload ([[HowToUpload|http://TiddlyWiki.bidix.info/#HowToUpload]]).
UploadPlugin uses Username and Password from UploadOptions stored in cookies to authenticate itself to [[store.php]].
French translation available as a separate tiddler UploadPluginMsgFR
!!UploadPlugin
*If the TiddlyWiki is viewed from @@local disk@@ :
**{{{<<saveChanges>>}}}
***display as ''save to disk''
***work as usual
**{{{<<upload>>}}}
***display as ''upload''
***after saving to disk, upload in the storeUrl directory.
*If the TiddlyWiki is viewed from @@website@@ and is @@readOnly@@ (in core TiddlyWiki since 2.0.6) :
**{{{<<saveChanges>>}}}
***print nothing
***has been disabled
**{{{<<upload>>}}}
***display as '''save to web''
***save in the uploadDir directory.
*If GenerateAnRssFeed in AdvancedOptions is set :
**generate the content of the RSSFeed
**upload the RssFile in uploadDir directory
**Caution : use the SiteUrl tiddler to specify the right url of the TiddlyWiki in the generated RssFile
*DisplayMessage
*Log upload action in UploadLog
hint : if UploadLog is the first tiddler in the Timeline Tab, no tiddler has been updated since last upload.
!![[store.php]]
*UserVariables to set :
//{{{
$AUTHENTICATE_USER = true; // true | false
$USERS = array(
'UserName1'=>'Password1',
'UserName2'=>'Password2',
'UserName3'=>'Password3'); // set usernames and strong passwords
$DEBUG = false; // true | false
//}}}
*method GET
**display an information page
*method POST
**if $~AUTHENTICATE_USER is ''true''
***presence and value of user and password are checked with $USER and $PASSWORD
**if toFilename already exists and backDir parameter specified
***rename toFilename to backupDir/toFilename.AAAAMMDD.HHSS.html
**copy temporaryUploadedFile to toFilename
** return status
!Usage :
{{{
<<upload>>
uses UploadOptions saved in cookies :
txtUploadUserName: username
pasUploadPassword : password
txtUploadStoreUrl : store script
txtUploadDir : relative path for upload directory
txtUploadFilename : upload filename
txtUploadBackupDir : relative path for backup directory
<<upload [storeUrl [toFilename [backupDir [uploadDir [username]]]]]>>
optional positional parameters can be passed to overwrite UploadOptions in this order.
}}}
Install the {{{<<upload ... >>}}} macro in SideBarOptions just below {{{<<saveChanges>>}}} macro.
!User manual
See HowToUpload
!Installation :
*Install the UploadPlugin as usual
*Upload the [[store.php]] file on your php aware webserver in your TiddlyWiki directory
*Protect your server against malicious upload. Two approaches :
**set $~AUTHENTICATE_USER to true in the [[store.php]] script
***configure $USER and $PASSWORD in the [[store.php]] script on your webserver
***set UploadOptions in conformity with [[store.php]]
**Use server protection :
***for Apache web server ([[for detail see Apache documentation|http://httpd.apache.org/docs/1.3/howto/htaccess.html]]) :
****configure and upload the [[.htaccess]] [[.passwd]]
***for other web servers see the appropriate documentation
*Configure an upload button, for example in the SideBarOptions
