ON THE PULSATION OF FINITE, VENTILATED CAVITIES

Abstract

The phenomenon of cavity resonance is explained as an interaction between the flow of the surrounding liquid and the compression and expansion of the contained gas. The general solution to the linearized problem of a symmetrical forebody performing symmetrical, harmonic motion, in an infinite medium, with a cavity pressure which is varying hermonically, is presented. The phenomenon of cavity resonance behind a stationary slender wedge in an infinite medium is studied in detail; the results show that self-excited pulsations at discreet frequencies are possible.
