摘要：

This paper analyzes the simulation results obtained by using FLUENT 6.1, simulation being carried out on supersonic inlet. A combination of turbulence models are adoptedsuch as k-RNG k- and S-A. The computation outcomes are checked by experiment results. Detailed analysis demonstrates that the numerical results obtained from the turbulence models can accurately forecast the pressure distribution trend in the inlet. However, for separation bubbles due to the mutual interference of the shock wave within the inlet boundary layer, the calculation predicts fewer bubbles than actually generated in the experiment. The RNG k- and SA turbulence models produces clearer wave structures in the channel.
