摘要：
The combustion of kerosene in a model combustion chamber at the flow Mach number M = 1.7 and a stagnation temperature of 1400 K is studied numerically. To ignite the fuel supplied through an axial injector and sustain its combustion, a pulsed periodic gas-dynamical effect is applied. The Reynolds-averaged Navier-Stokes equations are solved, which are closed by the k-& epsilon; turbulence model. Fuel combustion is reproduced using a single reaction. Calculations are carried out for various channel lengths. The gas-dynamical structure of flow during unsteady combustion of kerosene has been studied. The possibility of formation of a transonic flow regime has been investigated. The power of gas-dynamical effect is determined.
