| Abstract: | The operating process of liquid apogee engine (N2O4/MMH) thrust chamber is studied. By applying the SIMPLE algorithm with staggered grid, the numerical model is established. The atomization mechanism and decomposition combustion of hypergolic rocket propellant are considered in the model. The combustion performance was analyzed by using different cooling mass flow rate. The results of the numerical simulation are in agreement with those of theory analysis. Therefore, the research provides a theory reference for analysis of the rocket engine stability. |
