Research Programme and Methodology
The project is broken into work packages (WP) that are investigating specific areas as follows:
WP1 – Porous Material Development, Manufacture & Characterisation
This WP will develop porous, high temperature materials for aerothermal tests; provide understanding and measurements of both fundamental and derived properties; characterise material properties such as thermal conductivity, yield strength and flow porosity at elevated temperatures. This WP is primarily being undertaken by Imperial College London and Birmingham University.
WP2 – Flow & Heat Transfer Understanding
This research will investigate the complex interaction of the injected cooling flow with the oncoming flow field via advanced, laser based, experimental diagnostics; provide key data to validate numerical methods and give vital insight into the turbulent mixing processes. This WP is primarily being undertaken by Oxford University and Imperial College London.
WP3 – Measurement of Cooling Performance
This WP will provide the understanding of the cooling processes and evaluate the performance of porous cooled systems designed to reduce heat flux; investigate the mechanisms used to reduce heat flux by applying a variety of advanced measurement techniques; provide applied heat flux data for validation of numerical calculations and direct data for assessment for flight. This WP is primarily being undertaken by Oxford University.
WP4 – Numerical Modelling of Fluid/Structure
This WP will develop numerical methods to provide system predictability using experimental data from WP1, WP2 and WP3; investigate mixing and heat flux mechanisms in greater detail than can be obtained experimentally, using experimental data for validation application of advanced simulation methods to deal with disparity in geometric scaling. This WP is being carried out by Southampton University and Oxford University.
