摘要：

A supersonic flow in a channel with a variable cross section is numerically simulated in the case of ethylene injection along the channel under the action of a jet generating a throttling effect. The averaged Navier-Stokes equations closed by the k-epsilon turbulence model are solved. Ethylene combustion is modeled with the use of one reaction. The results are compared with experimental data on the pressure distribution over the channel wall. It is found that gas-dynamic pulses produce an irreversible effect on the flow structure. The formation of a transonic flow region and its structure are described.
