Abstract

Observations of the shape distortion during collapse of individual cavitation bubbles with maximum radii of about 0.5 to 1 cm have been made for collapse times of three to fourteen milliseconds; these observations are compared with theory. The bubbles were produced in superheated water and photographed at 3000 or 5000 frames per second. Growth was triggered by electrolysis and collapse was produced by pressurization. The distortions of bubble shape from spherical were found to be fairly well predicted by the theory of M. Rattray, when his perturbation parameter was adapted in a simple manner to the conditions used. A large variation in the collapse noise, due to bubble distortion caused by translational velocity, was observed to occur over the range of conditions tested.
