The structure of the flow with oblique detonation wave at the wedge for near-critical wedge angles

Supersonic inviscid flow of stechiometric hydrogen-air mixture around the wedge or cone is analyzed numerically with finite-rate chemical kinetics taking into account for big values of flow inclination. It's shown that near the surface of the wedge (cone) a complex wave structure with one ore two Mach configurations is realized. Transformation of this structure during the increase of the wedge (cone) angle and the transition from attached to detached detonation are considered.
