摘要：
A numerical model has been developed to predict the fast transient spray-combusting flows. This method is pressure based, noniterative, and applicable to flows at all speeds. Special emphasis is given to the overall behavior of nonlinear combustion instabilities in the liquid-fueled rocket engines. Computations were carried out for various combustion parameters such as initial spray conditions and baffle lengths. The present numerical model successfully predicts high-frequency combustion instability as well as fast transient flow. The baffle length as well as variations in droplet size have significant effects on engine stability. The numerical results indicate that the baffle can effectively suppress pressure oscillations.
