Abstract

Previous theoretical investigations of cavitation bubble dynamics have failed to consider the effect of a nearby wall or of translatory motion of the bubble.

It is shown that these effects are not small, but actually the analysis based on this assumption finally breaks down due to the large deformation of the bubble in the later stages of collapse. However, as the major portion of the time of collapse is spent in the low velocity motion, a meaningful time of collapse is obtained which, for the case of a bubble against a wall, is 20% longer than in the symmetric case. This agrees with the experiments performed in the Hydrodynamics Laboratory at the California Institute of Technology. The time of collapse is not appreciably affected by a translatory motion of the bubble of the magnitude encountered in the above experiments.
