Abstract

High temperature effects on shock wave-boundary layer interaction induced by two-dimensional compression corner have been numerically investigated. When a strong normal shock wave impinges on a ramp surface and reflects on the surface, steady flow is induced behind a normal shock wave and the flow separates near the compression corner and shock-wave/boundary-layer interaction region is formed. Since the static temperature of the flow is quite high enough for oxygen gas and nitrogen gas to dissociate, high temperature effects including dissociation and recombination of oxygen and nitrogen play very important roles in aerodynamic heating phenomena of shock-wave/boundary-layer interaction. The effects of chemical reactions on peak heating, peak pressure and separation length have been investigated. Also the effects of wall catalysis and free stream pressure to shock-wave/boundary-layer interaction flow fields are also discussed. The results show chemical reaction makes separation region smaller and surface catalytic effect is significant role to surface heating.
