Numerical simulation and investigation of working process features in high-duty combustion chambers

Basic concepts of a numerical simulation method of two-phase turbulent flows with combustion are stated. Results of computations in gas generators and combustion chambers of liquid-propellant rocket engines operating on oxygen and methane are presented. Features of the processes of evaporation, mixture, flow, and combustion of the propellant within chambers with tree types of injectors, i.e., coaxial-jet gas-liquid, liquid-liquid monopropellant and bipropellant impinging-jets, are studied.
