Numerical simulation of different regimes of high-speed combustion chamber
Abstract:
The flows in a model combustion chamber of a ramjet/scramjet engine with supersonic flow at the inlet are considered. The influence of the hydrocarbon fuel consumption on the combustion processes is studied based on Navier-Stokes equations of a reacting multicomponent flows. Numerical 2D simulation is performed on the K-100 supercomputer by means of OpenFOAM. It is obtained that depending on the fuel consumption the stationary and pulsating combustion processes are possible. The results agree qualitatively with known calculated and experimental data.
