A COMPARATIVE EVALUATION OF CAVITATION DAMAGE TEST DEVICES

摘要

A comparative evaluation of ,three types of test devices (Magnetostriction, flow and rotating disk) that are used for in-vestigations of cavitation damage is accomplished by means of a rational definition of intensity of cavitation damage.nThe 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.
