Distribution of ultrasonic cavitation intensities in a liquid system

Abstract
Measurements of the intensity of ultrasonic cavitation using a thermocouple probe are reported for an ultrasound frequency of 21.5 keps in water in both flat and round bottom tubes. The highest intensities were obtained when the flat bottom tube was located in the coupling fluid at a distance of one‐half wavelength above the transducer. The axial intensity profiles showed several local maxima.
