The characterization of acoustic cavitation bubbles – An overview
Ultrasonics Sonochemistry, 2011 Acoustic cavitation, in simple terms, is the growth and collapse of preexisting microbubbles under the influence of an ultrasonic field in liquids. The cavitation bubbles can be characterized by the dynamics of oscillations and the maximum temperatures and pressures reached when they collapse.
