Mach reflection (MR) is an essential component in the development of the shock theory, as well as the transition between regular reflection (RR) and Mach reflection. The hysteresis of Curved-shock reflection (CR) is not yet adequately understood due to the rotational complexity behind curved shocks. Here, an inverse Mach reflection (IMR), which is possible only in truly unsteady oblique-shock reflection (OR) transition, is found possible to be stable in CR. An analytical model for predicting the stable curved-shock IMR (CIMR) structure is established. Predictions of the Mach stem height and shock structure based on the model exhibit a great agreement with the numerical results. It is found that the compressive waves play a key role in generating the stable CIMR structure.
