ROES SOLVER WITH DIFFERENT TURBULENCE MODELS FOR 3-DIMENSIONAL HIGH-SPEED INLETS

A high-resolution Roe's solver combined with different turbulence mode ls is used to simulate the flowfield high-speed inlet that is characte rized by the complex phenomena of oblique-shock-wave-boundary-layer in teraction and interaction between oblique shock waves. The wall effect in a real three-dimensional flowfield is also considered. Fairly good agreement is obtained by comparing the numerical results of the turbu lent simulation with experimental data. It is found that the Mitcheltr ee one-equation model is more reliable than the others. The one-equati on model can also be used in simulating the high-speed inlet now with the good accuracy.
