This paper deals with the dynamics of a cluster of bubbles. Governing equations derived in the first report are solved to predict collapse motions of the cluster of bubbles under sudden and stepwise increases in pressure of the liquid. A test computation is first performed on the collapse of two vapor bubbles in the neighborhood of a plane rigid wall and is found to be in good agreement with a result obtained by the boundary element method. The collapse motions of one through nine bubbles placed in different configurations are analyzed. It is shown that three-dimensional deformations of the bubbles are greatly affected by traslational motions of individual bubbles. The results show that the pressure at the boundaries of the interacting bubbles can be higher than that of an isolated bubble. Effects of liquid viscosity are also discussed.
