Cavitation dynamics. 3: Thresholds and the generation of transient cavities
Abstract
Dynamics of small argon bubbles under the influence of an acoustic pressure field have been studied using a mathematical formulation derived previously (J. Acoust. Soc. 57, 1379-1396 (1975)). Calculation of the maximum pressure in a collapsing bubble and work done by expanding bubbles show there are two cavitation pressure thresholds -- one for the onset of cavitation activity and the other for a decrease in cavitation activity.
