Scaling Laws for Incipient Cavitation Noise

Abstract

The noise produced by the motion or a body through a liquid differs from that produced by the motion of a body through a gas because of the possibility or cavitation in the liquid case. An adequate theory or cavitation and cavitation noise is not yet available, but the application or dimensional analysis together with the theoretical information so far obtained can yield scaling laws for this flow situation. In section II, a brief dissussion will be given or the scaling laws for hydrodynamic noise in some cases of non-cavitating flow; this discussion is included tor oompleteness. In section III, a summary or the present information on the scaling law. for incipient cavitation noise will be presented.
