Numerical investigation of an effusion cooled thermal protection material

Kurzfassung

A simplified one dimensional model for an effusion cooled wall is described which was implemented into the DLR-TAU code. The surface temperature is iterated via equilibrating the radiation heat flux together with a simple energy gain of the coolant versus the thermal and diffusion heat fluxes from the flow field. Under these assumptions the model shows the influence of the effusion mass flow rate on the flow field topology (separation prediction) and the effectiveness of different coolants.
