Abstract: Numerical simulation of supersonic flow of viscous heat-conducting gas around the ballistic model (HB-2) for various angles of attack $\alpha = 0, 8, 16^\circ$ and temperatures of the model surface was carried out on the basis of a compact version of the hyperbolic system of quasi-gasdynamic equations.
Three-dimensional features of the flow and heat flux’s dependence on the angle of attack and wall temperature were investigated. The presence of an angle of attack leads to the formation of two longitudinal vortices on the model’s leeward side near the symmetry plane. These separation regions significantly affect the distribution of the heat flux on the leeward surface.

Keywords: quasi-gasdynamic system of equations, HB-2 model, isothermal wall, heat flux density.
