A BULK CAVITATION THEORY WITH A SIMPLE EXACT SOLUTION

Abstract

A theory of bulk cavitation is presented in which an equation governing the motion of the water surface is derived. This equation is found to have a simple exact solution with which calculations can be performed without a computer. This solution not only yields the results of Walker and Gordon for the closure depth and time, but also predicts the complete surface velocity history rather than just a straight line model of the surface velocity history. Simple exact equations for the surface slab thickness history and the surface displacement history are also derived. The theory is found to be physically plausible and is in reasonable agreement with the experimental data of Walker and Gordon.
