Abstract
The cavitation process in a pulsed focused ultrasonic field is investigated. For the first time, an abnormally long delay (up to several minutes) in the onset of non-stationary cavitation relative to the moment the ultrasound is switched on has been recorded. A methodology for selecting field parameters that enables control of the dynamics of cavitation region development is proposed.
