Analytical Model for Predicting the Dynamic Behavior of Cavities

Abstract

The first iteration in the development of an analytical model for predicting the dynamic behavior of cavities is near completion. A model to predict the cavity pressure and mass attrition needs to be developed. The predictions of the present model for the diameter and length of steady-state cavities agrees very well with experimental data. The need for reliable drag coefficients at high cavitation numbers is cited and it is recommended that future experimental work to be conducted at ARL include the measurement of drag forces in order to correct this deficiency.
