Combustion of Ethylene and Kerosene in a Supersonic Flow at Low Mach Numbers

Combustion of ethylene and kerosene in flows with Mach numbers M 2 is numerically studied. Flow throttling with the use of a side jet of compressed air is provided for igniting the fuel injected through an axial injector and for supporting its combustion. The Reynolds-averaged Navier–Stokes equations closed with the – turbulence model are solved. Fuel combustion is modeled by one reaction. The possibility of formation of a transonic flow is considered. The gas-dynamic structure of the flow in the channel in the case of kerosene combustion is investigated for the Mach number M = 1.7 and stagnation temperatures of 1400 and 1500 K. The computations are performed for various values of the limiter of turbulent kinetic energy generation.
