摘要：

Several kinetic models of hydrogen oxidization are compared for the purpose of selecting the reaction mechanism to describe the chemical interaction in numerically modeling the detonation combustion of a hydrogen-airmixture. Within the framework of the chosen kinetic model the possibility of stabilizing a detonation wave in a stoichiometric hydrogen-airmixture arriving in a plane channel at a supersonic velocity is discussed. For certain inflow Mach numbers a method for determining the shape of the channel, in which a stabilized detonation wave can be formed without energy supply, is proposed. In the case of the M0 = 5.5 combustible mixture flow past a semi-infinite symmetric plane body aligned with the flow the structure of the detached detonation wave stabilized ahead of the obstacle is studied.
