Abstract:
The simulation of multicomponent nonequilibrium dissociated air flow over catalytic surface of blunt bodies, moving along aerodynamic reentry trajectory is considered. The hypersonic viscous shock layer theory including nonequilibrium.chemical reactions and multicomponent diffusion is used as initial mathematical model. The characteristic property of suggested numerical procedure is that it doesn't need preliminary solution of the Stefan–Maxwell equations with respect to diffusion fluxes and doesn't imply symmetric planes existence in the flow. The influence of attack and slipping angles, heterogeneous recombination rate is investigated. It is obtained, that for non zerr incidence and slipping a limited region arises on the lateral surface of the body, where the heat flux exceeds its values at the stagnation point. The accuracy of the binary similarity approximation was estimated.
