| Abstract: | The NND scheme proposed by academician Zhang Hanxin has been used to simulate numerically the interior flow-fields of a 2D ex-internal compression supersonic inlet The interference of shockwave-shockwave and shockwave-boundary layer have been simulated preferably The method of solution applied Flux-Vector Splitting in order to improve the computational efficiency, accuracy and stability By means of the numerical simulation, the performance parameters of internal flow-fields have been predicted, and the effct of flight condition and geometry parameters on the performance parameters have been analyzed |
