The paper studies of the cellular detonation wave interaction with supersonic reacting flow in the scramjet combustion chamber. Comparing the flow fields for the details and the reduced chemical kinetics models is allowed verifying the acceptability of the proposed simplified kinetic scheme. The possibility of using pulsating detonation for the ignition intensification in the scramjet combustion chamber is shown. Calculation of the detonation wave interaction with nonpremixed hydrogenair mixture is made. The ability to influence on the hydrogen-air mixing process by means of detonation tube is detected. The effect of tube sizes to intensification of hydrogen air mixing in the flow at channel with a cavity is calculated.
The results of numerical simulation of the detonation wave interaction with a circular obstacles staggered are presented. The calculations were carried out for a prepared stoichiometric hydrogen-air mixture. The influence of the rows number, the step between them and the scale effects on the detonation suppression was investigated. The modes of detonation suppression and re-initiation were obtained.
