COMBUSTION OF KEROSENE IN A SUPERSONIC FLOW AT MACH NUMBER M = 1.7 UNDER THE ACTION OF GAS-DYNAMICAL PULSES

The combustion of kerosene in a model combustion chamber at the fl ow 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 eff ect is applied. The Reynolds-averaged Navier–Stokes equations are solved, which are closed by the k–ε turbulence model. Fuel combustion is reproduced using a single reaction. Calculations are carried out for various channel lengths. The gas-dynamical structure of fl ow during unsteady combustion of kerosene has been studied. The possibility of formation of a transonic fl ow regime has been investigated. The power of gas-dynamical eff ect is determined.
