Shock Wave Propagation in Tissue and Bone
Studying the physical and biological mechanisms of extracorporeal shock wave therapy (ESWT) requires modeling the propagation of strong shock waves through tissue and bone. Interfaces between different biological materials lead to reflections and focusing shock waves and the creation of strong rarefaction zones and cavitation fields. I will discuss recent numerical work using high-resolution finite volume methods in which each grid cell is allowed to have distinct material properties. Sharp interfaces either occur at cell edges (if an appropriate geometry-conforming grid can be obtained) or are represented by averaging the material properties over grid cells on a Cartesian grid. In either case, logically rectangular grids with adaptive mesh refinement are used to efficiently deal with multiscale problems where the medium has heterogeneities at various length scales.
