Abstract: Combustion of ethylene and kerosene in flows with Mach numbers $\mathrm{M}\le 2$ 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 $k{-}\varepsilon$ 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 $\mathrm{M}=1.7$ and stagnation temperatures of $1400$ and $1500$ K. The computations are performed for various values of the limiter of turbulent kinetic energy generation.

Keywords: combustion, ethylene, kerosene, supersonic flow, throttling jet, transonic flow.
