  We consider the collapse behavior of cavitation bubbles near walls under high
ambient pressure conditions. Generic configurations with different stand-off
distances are investigated by numerical simulation using a fully compressible
two-phase flow solver including phase change. The results show that the
stand-off distance has significant effects on collapse dynamics, micro-jet
formation, rebound, and maximum wall pressure. A relation between cavitation
induced material damage and corresponding collapse mechanisms is obtained from
pressure-impact data at the wall. We analyze the resolution dependence of
collapse and rebound and the observed maximum pressure distributions. The
comparison of the results on six different grid resolutions shows that main
collapse features are already captured on the coarsest resolution, while the
peak pressures are strongly resolution dependent.
