The numerical simulation method, developed in Keldysh Research Centre, is used for the research of the influence of interaction of jets from the injectors on flow, mixing and propellant combustion processes in sub-scale multiinjector combustion chambers. Sub-scale combustion chambers using coaxial-jet and jet-centrifugal injectors, operating to the gas-liquid scheme and propelled by oxygen and hydrocarbons (kerosene) are considered.
