Аннотация:The numerical investigation of detonation combustion of a stoichiometrical hydrogen-air mixture flowing at a supersonic velocity into a plane channel has been carried out with the purpose of ascertaining a channel form that guarantees detonation stabilization in the flow without any expenditure of energy. So the possibility of stabilization of a formed detonation wave in the combustible gas mixture flowing into the plane channel with narrowing has been determined. The stability of the flow with stabilized detonation in the channel with narrowing to strong disturbances has been examined. For some Mach numbers of the incoming flow, the method of determination of the channel shape which provides detonation initiation and its stabilization in the flow without any energy input is proposed.
