Scale Effects in Cavitation Erosion of Materials

Abstract:

This work presents a mathematical model describing the cavitation erosion of materials. The model of cavitation erosion is based on Weibull’s distribution. The model describes the influence of material properties and also dimensions of the eroded area and volume of the eroded material on cavitation erosion curves i.e. cumulative volume loss and volume loss rate as a function of time of cavitation loading. In addition, there is a possibility to define cavitation resistance of materials, upon the base of the adduced model.
