Mach number effects on shock-bubble interaction (Q5950159)

The authors investigate the interaction of a shock wave with a bubble. Using high resolution Godunov type methods and an implicit solver, simulations have been conducted on the base of Euler equations for various incident shock Mach numbers \(M_S\) in the range of \(1.22\leq M_S\leq 6\). At higher Mach numbers, larger deformations of the bubble occur, a secondary reflected shock wave arises upstream of the bubble, and the initial ``\(C\)-shaped'' vortical structure changes to a circular-shaped structure. With increasing incident Mach number, the speed of the jet also increases.
