  • The analysis model of self-ejector(ejector for short,including cylindrical ejector and second-throat ejector) was set up in liquid rocket engine.The two equation κ-ε model was employed to simulate the turbulence.The performances and the flow field features of cylindrical and second-throat ejector were gained in same gap.According as these flow fields,the site of the shock wave,the full flow in nozzle,the coefficients of ejecting were calculated.The numerical value was compared with hot fire test value in vacuum cabin,both are same.
