Abstract
The paper presents experimental, numerical, and analytical work aiming at the reexamination of the current state of knowledge regarding the transition from inverse Mach reflection (InMR) to transitioned regular reflection (TRR) on a concave cylindrical surface. The obtained experimental and inviscid numerical wall angles at the InMR-TRR transition agree well with each other, while their values are considerably higher as compared to the experimental results of the early 1980s, which can be largely attributed to lower resolution of the latter. A number of available analytical approaches are compared with the present experiments and simulations, leading to the conclusion that there is still no fully satisfactory analytical model of the transition.
