【Abstract】 A Computational Study is conducted to investigate the effects of injection ports in a two-dimensional, convergent-divergent nozzle, for shock vector control method. The finite volume method is used to solve the 2D Reynolds Averaged N-S equation coupling the two-equation RNG k-ε turbulence model and nonequilibrium wall functions. In the numerical procedure, the second-order TVD scheme is used. Results from the numerical simulation are in excellent agreement with experimental results.$$$$更多还原
