Abstract

The bubble size distribution in an acoustic cavitation streamer structure at 20 kHz is measured by photographic means. Recalculation of the bubble equilibrium radii leads to values in the range of a few micrometer. This is compared to previous results and a theoretical estimation based on surface stability of oscillating spherical bubbles.
