Abstract: The present numerical study deals with a possibility of ensuring hydrocarbon fuel combustion in a high-speed flow in a short axisymmetric channel by means of hydrogen and air side (annular) jets eliminating shock waves, which are the main source of total pressure losses. The Reynolds-averaged Navier-Stokes equations with the $(k-\varepsilon)$ turbulence model are solved. A stable transonic mode is obtained in the first section. A pulsating mode of hydrogen burning with destruction of the shock wave structure of the flow is obtained in the second section. The physical mechanisms of the observed processes are studied.

Keywords: hydrocarbon fuel, hydrogen, combustion, throttle jet, transonic mode.
