Abstract
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 k-ε 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 1 400 and 1 500 K. The computations are performed for various values of the limiter of turbulent kinetic energy generation.
