Ultrasonic cavitation intensity of aqueous sodium lauryl sulfate solutions

Abstract

The ultrasonic cavitation noise intensity as a function of the concentration of aqueous sodium lauryl sulfate solutions has been measured. The cavitation noise decreases with increasing concentration (decreasing surface tension) until a concentration of 0.0128 M is reached. Above this concentration a sharp increase in cavitation noise is observed. The possibility that micelles serve as cavitation nuclei is discussed.
