Flow analysis and validation of rocket ejector mode for rocket based combined cycle

Upwind-scheme limited-volume methodology was employed to solve Navier-Stockes equation, the flow-field in the inlet/mixer/combustor/nozzle/ejector-rocket of a RBCC test model was simulated, the sophisticated flow structure in the duct was analysized, the principle of rocket-ejector pumping and mixing ability of the model was discussed, and finally, the calculation was validated by the experimentation with good agreement each other. All this results provide some theoretical basis for the deep research about RBCC ejector mode operation and parameter optimization.
