The bubbly cavitating .ow generated by a lithotriptor is computed using an ensemble averaged two-phase .ow model. The time-dependent, compressible .ow computation is divided into two separate calculations: the refocusing of a spherical pulse by an ellipsoidal re.ector, and the evolution of the steepening wave including the cavitating bubble cloud it generates. The .rst computation is single phase and is done in prolate spheroidal coordinates in order to have the surface of the ellipsoidal re.ector aligned with the computation grid. The output of this simulation is then fed to the two-phase cylindrical coordinates domain. Preliminary results and qualitative comparison to experimental observation are presented.
