Paper Abstract

Shock wave interaction with a rotating circular cylinder is numerically and experimentally investigated. It is shown that the transition from regular reflection to Mach reflection on the lower surface of a rotating cylinder where cylinder motion is the same as the incident shock motion, is more quickly promoted than that on the upper surface. Numerical calculations solving the Navier-Stokes equations using extremely fine grids further reveal that the reflected shock transition from RR yields MR is either advanced or postponed depending on whether or not a surface motion favors the incident shock wave.
