Abstract

Thermochemical nonequilibrium flow computations are carried out for the purpose of reproducing surface heat transfer rate at the Space Shuttle orbiter nose-cap region during the reentry flight. For an accurate calculation of aeroheating environment at the nose-cap region, we employ a prismatic unstructured mesh system for avoiding mesh singular lines often appearing in structured meshes. Developed numerical code is first verified through comparing with the Fay and Riddell analytical formula for heat transfer rate at the stagnation point of a blunt body. Calculated results for the Space Shuttle orbiter show that the present numerical method can reproduce the flight data very well at the stagnation point, but not so well for off-stagnation points.
