英文摘要	In this Letter, the dynamic effect of rotation on unsteady shock interaction between an oblique shock wave and bow shock ahead of an elliptic cylinder is numerically investigated. First, a non-deforming grid method based on a non-inertial reference frame is applied for supersonic/hypersonic flow around an arbitrarily moving body. A simulation considering a rotating elliptic cylinder is then conducted at Ma5 with forced-oscillation approach. The results show that the shock interaction structure during rotation has obvious hysteresis compared with the static condition, and transition among different types of shock interaction is also affected by rotation direction and speed. The mechanisms are briefly addressed. Published under an exclusive license by AIP Publishing.
