Abstract
Noise emitted by cavitating regions in a liquid, e.g. from a cavitating ship propeller, shows a complicated spectral density distribution.
In ship hydrodynamics one is interested in the way in which various types of cavitation (bubble-, vortex-, sheet cavitation) emit sound and, most importantly, in the scaling rules for the emitted sound. The more so, now that it is possible to do model tests with ships with the full scale cavitation number.
In this lecture we review developments in this field since the Fitzpatrick & Strasberg ONR paper in 1956, in particular the gradually gained insight that clouds of cavitation bubbles, as distinct from single bubbles, contribute significantly to the emitted sound. Following this, attention is given to the question how such clouds are generated during the lifetime of a cavitation sheet.
