Purpose of this paper is numerically to make a resolution of interactions between hypersonic reacting flows and wedges. Gas utilized in this study is a stoichiometric hydrogen and oxygen gas mixture which composes 19 elementary reactions with 8 chemical species. A finite difference approximation used in the simulation consists of the MacCormack-TVD scheme and the semi-implicit scheme which treates implicitly chemical reaction terms. The flow Mach number and the half vertical angle of wedge as flow parameters were changed from M=5 to 10 and θ=15 to 45 degree, respectively. It was shown in the inviscid flow that an oblique shock wave front and an detonation wave front coexist on the wedge surface depending on a combination of the Mach number and the wedge angle. In the viscous flow model, only the detonation wave front was observed within the content of the calculation conditions.
