Abstract
The boundary integral method is employed to model the dynamic behaviour of cavity interactions in a variety of environments. The surrounding fluid is assumed to be incompressible, inviscid and irrotational. The study reveals a wide range of responses that may be found when cavitation bubble interactions are strong, clearly indicating the significance of including the dynamics of bubble interaction in any large-scale model of two phase flow. In the case of transient cavity collapse, the occurrence of a high-speed liquid jet is found to depend sensitively upon any asymmetries associated with the flow field. The calculations are found to mimic experimental observations of bubbles near a rigid boundary, near a free surface and in an axisymmetric stagnation point flow. The results also provide additional information on the bubble shape not recorded by high-speed cameras, as well as allowing estimates of the hydrodynamic pressures.
