Compressible Multicomponent Flow Calculations and Shock-bubble Interaction

We report on the development of a numerical method to simulate two-dimensional compressible multicomponent flows. Our scheme is shockand interface-capturing, quasi-conservative and high-order accurate. We validate it for two-dimensional problems including shock-bubble interactions and examine the shockinduced asymetric collapse of a cylindrical gas bubble in water, where wave strengths and pulse durations are chosen to model conditions relevant to shockwave lithotripsy. In particular, we determine how the pressure at the surface of a nearby wall depends on the various properties of the pulse and on the geometry. We also describe the extension of the method to axisymmetric geometry and show preliminary results.
