Description

A left moving shock wave propagates first through the stiffened gas before it hits a stationary bubble, which gains speed and loss its circular shape. After the shock wave hits the bubble, circular pressure waves are created, while a pair of vortices appears on the tail of the bubble, increasing the pattern complexity of the interface. This example is a classic multiphase flow example [1], here we use it to test our two-phase multiphase flow solver.
