Numerical simulation of windward vortex shocks about supersonic slender

摘要: 旋成弹体在大攻角超声速流动中其迎风面上有时会出现一种迎风激波. 采用非定常雷诺平均的Navier-Stokes方程以及两方程k\omega-sst和代数B-L湍流模型成功地模拟了该现象，验证了该迎风激波是由于流场主旋涡导致超声速流动偏移造成的涡诱导激波的一部分的结论.

Abstract: Vortex shocks may be found inside the bow shock wave onsupersonic slender bodies at a high angles of attack. A numerical studyis performed by using Reynolds-averaged Navier-Stokes equations ,k\omega-sst and Badwin-Lomax turbulence models. It is shown that thevortex shocks are associated with the virtual double cone-like deflection of thesupersonic stream by the primary vortices. -
