Abstract
The effect of the parameters of a pulsed-periodic side jet on combustion of a hydrocarbon fuel in an axisymmetric channel flow with the Mach number of 1.7 is studied numerically. The Reynolds-averaged Navier-Stokes equations closed with the k-e turbulence model are solved. Fuel combustion is modeled with the use of one reaction. It is demonstrated that the temperature of the gas generator for the jet produced only a minor effect on the shock wave structure of the flow. The key role belongs to the pressure of side jet injection. A transonic flow structure is obtained.
