A COMPARATIVE EVALUATION OF CAVITATION-DAMAGE TEST DEVICES

Abstract

A comparative evaluation of three types of test devices (Magnetostriction, flow and rotating disk) that are used for investigations of cavitation damage is accomplished by means of a rational definition of intensity of cavitation damage. The intensity of cavitation damage is defined as the power absorbed per unit area of the damaged material surface. It is estimated by multiplying the average depth of erosion per unit time by the strain energy of the material. The intensity of cavitation damage of the A.S.M.E. Standard Magnetostriction Device is approximately one erg per second per square centimeter. Similarly the intensity of the rotating disk device used by Thiruvengadam is also one erg/sec/cm squared. The most intense laboratory device so far used is the rotating disk device of Rasmussen. The least intense device is the Verturi type flow device used by Hammitt.
