| Abstract | The reflection of asymmetric nonstationary shock waves is analytically and numerically studied in this paper. An analytical approach, which is a combination of the shock dynamic and shock polar methods, is advanced to predict the reflection wave configurations. The numerical simulations are performed by the finite volume method based on the second-order MUSCL-Hancock scheme and the HLLC approximate Riemann solver, with the self-adaptive unstructured mesh. It is found that the transition between the overall regular reflection and overall Mach reflection in the asymmetric nonstationary reflection agrees with the detachment criterion, which is analogous to the reflection in pseudo-steady flows (i.e. shock reflection over a wedge). Some special reflection wave configurations, which have never been observed in steady or nonstationary shock reflections so far, are found to exist in this asymmetric reflection. Furthermore, the domains and boundaries of various overall reflection wave configurations are analytically predicted, and the effect of mis-synchronization is also discussed. |
