摘要

In this work, we present numerical simulation results for shock-induced bubble collapse dynamics near tissue-like compliant gelatin phase. We use a sharp-interface model for multiple materials to represent the ambient liquid (water), the non-condensable gas phase (air) and the gelatin phase. Employing multi-resolution techniques, we investigate the complex interface dynamics and compare the results with experimental data from literature. Our aim is to understand and quantify the mechanisms observed during extracorporeal shock-wave lithotripsy or sonoporation. Therefore, latestage dynamics of the bubble collapse and tissue penetration are presented.
