An investigation of acoustic cavitation produced by pulsed ultrasound
investigationofa00bruc.pdf (4.838Mb)Abstract
Transient cavitation produced by pulsed ultrasound in the MHz
range has been investigated. First, a theoretical background which
develops bubble motion in general and focuses specifically on transient
cavitation is presented. Second, the development of an apparatus
which is designed specifically for studying this type of cavitation is
discussed. Third, the use of the apparatus to make measurements of
cavitation thresholds at various frequencies, pulse durations, and pulse
repetition rates is discussed. Finally, results of the cavitation threshold
measurements are interpreted using theories developed earlier.

Fluid-interaction and cavitation effects on a surface ship model due to an underwater explosion
(Monterey, California. Naval Postgraduate School, 1996-09);A surface ship subjected to an underwater explosion is exposed to shock waves over a short period of time which can vary in magnitude based on charge type, size, and location. The energy of those waves impinging upon the ... -
