Abstract
The Vortex Combustion Cold Wall is an innovation cooling method for liquid rocket engine combustion chamber, which has the advantages of simple structure, low-cost and high reliability. Based on the introduction the principle of Vortex-cooled Combustion Chamber (VCCC), the vortex flow configuration was analyzed and the distributional characteristics of bidirectional vortex was demonstrated. By means of the cold flow simulation, preliminary analysis of vortex flow configuration was performed. Velocity and energy decreased in the flow field due to viscous can affect the efficiency of propellant mixing and combustion under reactive flow conditions. Optimizing the incidence angle of oxidizer nozzles shows that the oxidizer nozzle with certain slope angle can enhance the velocity and vorticity of inner vortex regions and improve the combustion efficiency of propellants in VCCC.
