摘要：

The collapse of a low density cloud of bubbles is studied using matched asymptotic expansions. Equations describing the motion and deformation of an individual bubble accounting for its interaction with the other bubbles in the cloud are derived. Numerical results for the case of a symmetrical cloud configuration show a dramatic increase of the pressure generated at the end of the collapse due to collective effects. This explains the observed high erosion associated with cloud cavitation.
