Abstract: Structural changes in a supersonic flow in a variable-section channels with axial injection of kerosene induced by the action of a jet generating a throttling effect are numerically simulated. Reynolds-averaged Navier–Stokes equations closed by the ($k{-}\varepsilon$) turbulence model are solved. Kerosene combustion if modeled by equations of simplified chemical kinetics. The evolution of the processes in the channel is analyzed numerically and analytically for different types of the fuel (hydrogen, ethylene, and kerosene), and comparisons with experimental data are performed. It is found that high-intensity gas-dynamic pulses have to be used to form a transonic region in the case where kerosene is used as a fuel.

Keywords: kerosene combustion, axial injector, supersonic flow, throttling jet, transonic regime.
