Rotating Tank
Location: Fluids Laboratory/Central areaDesign of rotating tank
The study of rotating fluid flows, either dominated by centrifugal or Coriolis forces is studied experimentally in our new rotating tank facility. There are two interchangeable platforms, a small 1m diameter platform which rotates at 1 rev/s and a larger 2.5m platform which rotates at much slower rates. The construction of the platform was funded by the Equipment Grant associated with an EPSRC Advanced Fellowship, with further modifications to study centrifugal separations constructed with a Royal Society Equipment Fund. The platform was designed by a Fourth Design Team and further modifications by Andre Nicolle, Mark Landeryou and Christian Klettner. Final year students undertaking their dissertation with the group are providing new design elements to the platform.

Coastal and Deep Water Wave Tank
Location: Fluids Laboratory/Side area
In 2006, the redesign and commissioning of the coastal and deep water wave tanks in the fluids laboratory were completed. The design led by Dr Kevin Drake and Edinburgh Design team. This was funded by SRIFII funding, led by Dr Eames, in collaboration with Prof Simons (Civil Engineering, UCL) and Dr Diane Horne (Birkbeck College). This is a major facility for UCL, enabling detailed studies of waves, currents and their complex interaction with fixed and moving bodies.

rule Enviromental Testing Tanks
Location: Eames Laboratory
Also in 2006, environmental testing tanks were completed in the Eames Laboratory, to permit the study of vortices and gravity currents in constrained geometries. This facility was designed by Dr Alan Hinds (Mathematics), supervised by Dr Robb McDonald and Prof Ted Johnson, and funded by UCL Central Research Fund. Some of the initial results from this facility are now coming to fruition.

Computing Laboratories
Location: Room 401

We use advanced tools to investigate multiscale flow phenomenon numerically. We have developed inhouse FEM codes, validated for planar and axisymmetric flows to Re=5000. The codes have been written with MPI to test on our  8 node cluster, with an imminent roll out to UCL's research computational facility. The code has been developed by Andre Nicolle and Mark Landeryou and with further extensions to include ALE by Christian Klettner. We have workstations and computers equiped with a wide variety of software drawing  on shareware and commercial software to study fluid flows.

Laser Diagnostics
Location: Fluids/ IC Engine Laboratory
Funding from SRIFII enable the Department of Mechanical Engineering to purchase advanced laser diagnostics to study and measure flow fields.
