The combustion of hydrocarbon fuel at the Mach number M = 1.7 is studied numerically. A transverse air stream is used to ignite the fuel supplied through the axial injector. The Reynolds-averaged Navier-Stokes equations closed by the k-ε turbulence model are solved. Fuel combustion is simulated using a single reaction approach. The possibility of transonic flow formation has been investigated. The gas-dynamic structure of kerosene fuel combustion is studied for a flow with the Mach number M = 1.7 and stagnation temperature of 1500 K.
