Propagation of a planar shock wave along a convex–concave ramp

The propagation of a normal shock wave along coupled convex–concave surface equal radii has been analysed experimentally and numerically in this study. experimental numerical studies were conducted using similar geometry as that used by Ram et al. ( J. Fluid Mech. , vol. 768, 2015, pp. 219–239) for studying the transition from regular reflection to Mach reflection. Many interesting flow features such transitions over ramp, characteristics induced behind development stationary separation have observed results are validated with data. While ramp found depend mainly on geometry, concave region vary numbers.
