Abstract This work presents the results of two-dimensional numerical simulation of processes, arising from the interaction of an incoming flow of a well-mixed stoichiometric hydrogen-air mixture with a wedge in a bounded region at high Mach velocities using Navier-Stokes type equations taking into account chemical interactions. The Mach number of the incoming flow from 9 to 12 were considered. Various wave configurations were obtained depending on the velocity of the incoming flow. For the flow Mach number of 9, the presence of a detonation wave perpendicular to the flow was obtained. For high flow velocities, another similar wave configuration of the same type was obtained.
Highlights A simulation of a flow interaction with a wedge at high Mach speeds was carried out A well-mixed stoichiometric hydrogen-air mixture was considered Hong's kinetic mechanism was considered Two wave configurations were obtained depending on the velocity of the flow For Mach number equal 9 the detonation wave perpendicular to the flow was obtained
