Acoustic microcavitation: Its active and passive acoustic detection

Abstract:

In this work acoustic microcavitation in water is studied primarily at 0.75 MHz and 1% duty cycle. To detect cavitation, two kinds of acoustic detectors are used. The first one is an unfocused, untuned 1‐MHz receiver transducer that serves as a passive detector. The other one is a focused 30‐MHz transducer that is used in pulse‐echo mode and is called the active detector. Cavitation itself is brought about by a focused PZT‐8 crystal driven in pulse mode. The active detector is arranged confoc...
