Research Studentship: Transpiration Cooled Systems for Hypersonic Vehicles

Research Studentship in Transpiration Cooled Systems for Hypersonic Vehicles

Supervisor: Prof Matthew McGilvray

Details of Post

The two studentships are part of a larger EPSRC funded project on Transpiration cooling systems for hypersonic flight and gas turbines. This research programme includes collaborators at Imperial, Birmingham and Southampton Universities and is a multi-disciplinary programme from materials development to numerical analysis of the flow.

Transpiration cooling is the addition of a coolant through a porous material into the sub-layer of boundary layer. This active cooling system has potential use in hypersonic vehicles where an extremely hot plasma is generated when flying through an atmosphere, resulting in enormous heat fluxes to the vehicle. Transpiration cooling can reduce the overall heat-flux through internal cooling of the material and the coverage of the external surface with a cool gas. This technology could enable the reusability of future space planes, moving past current one-mission ablative heat shield technology. The current research will underpin the fundamental understanding required to make the technology a reality in future flight vehicles.

The successful students will specifically focus on experiments to understand how the injection of a coolant through a porous material will affect the transition process in the boundary layer. Experiments will be undertaken in the University of Oxford's new hypersonic wind tunnels which can generate speeds of us to 25,000 miles per hour. There will be the opportunity of applying novel laser diagnostic techniques to understand the flow processes with supervision from Dr Benjamin Williams.

The student will be expected to interact and present their work to the other project partners including those at other universities and industrial partners. It is expected that the student will submit their work and present at the top international conferences in the field.
