THE BEHAVIOR OF AIR BUBBLES IN ACOUSTIC FIELDS

Abstract

Gaseous cavitation poses a severe limitation on sonar performance. Simple vacuum experiments, a search of the literature and observations of the behavior of air bubbles in standing wave fields were made in order to gain information useful to the design and fabrication of sonar transducers and domes. Subjects discussed include bubble resonance and damping, radiation force, microstreaming and rectified diffusion. A set of simple rules is set down to help guide the sonar designer in order to minimize the effects of gaseous cavitation.
