【Abstract】 An new uncoupled method was introduced to simulate numerically nonequilibrium flow which had the stiffness problem. The flow phenomenon of H 2/O 2 combustion induced by shock was simulated with the method, based on N S equations and NND2M scheme. The results indicated that the method was simple and efficient in the application to multi component and multi reaction flow.更多还原
