Shock Induced Cavitation

Abstract

Shock test planning for surface ships renewed interest in shock induced cavitation as a mechanism of damage to naval ships. A program for further investigation of cavitation is provided here: a review of past theory and experimental data, extending back to WWII; a refinement of theory providing for after flow in the incident shockwave; a review of hull plate loading involving local cavitation; and prediction of secondary pressures and impulses generated by combined effects of bulk cavitation and sea-bottom reflection. Sea-bottom reflection characteristics for a specific shock test site are generally known poorly. Analysis indicates that an unfortunate choice of test site could produce large reflection-and-cavitation effects.
