Abstract: Starting of an air-breathing engine with fuel injection distributed along the combustion chamber is numerically simulated. Issues of principal importance are the presence of a compressed are jet generating a throttling effect and preliminary deceleration of the flow to transonic velocities. Averaged Navier–Stokes equations closed by the SST, SST $k-\omega$, or $k-\varepsilon$ turbulence models are solved. Hydrogen and ethylene combustion is simulated by one reaction. The computations are performed for various values of the turbulent kinetic energy in the flow. A pulsed transonic regime of hydrogen and ethylene combustion is discovered.

Keywords: hydrogen combustion, supersonic flow, transverse jets, transonic flow regime.
