Zusammenfassung:The nozzle is an important component for thrust produced by scramjet engine. The flow field numerical simulation was conducted in NASA single expansion ramp nozzle experiment model. The flow field within nozzle was simulated using the Fluent CFD code which employed RNG k- epsilon turbulence model to study the effect of the inlet parameters including specific heat ratio, NPR, Mach number, temperature, which showed the internal flow field's diversification rule and performance changed with various flow parameters of nozzle. The results are useful for further integrated design of scramjet combustor/nozzle.
