An Investigation of Acoustic Cavitation Produced by Pulsed Ultrasound

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. Keywords: Microcavitation, Cavitation threshold, Theses, Threshold detection, Transducer calibration.
