Heat flux in supersonic flow past ballistic model at various angles of attack and wall temperatures

摘要

Supersonic flow of viscous heat-conducting gas around the ballistic model HB-2 and the resulting heat flux for M = 3, angles of attack alpha = 0 degrees, 8 degrees, 16 degrees and various model surface temperatures were numerically studied using the compact version of the hyperbolic system of quasi-gasdynamic equations (CHQGD).Three-dimensional features of the flow structure and heat flux's dependence on the angle of attack and wall temperature were investigated. Longitudinal vortices on the model's leeward side near the symmetry plane were observed for alpha = 16 degrees. These flow separation regions significantly affect heat flux distribution on the model's leeward surface.
