A CONSIDERATION ON SCALING LAWS OF CAVITATION EROSION

This paper presents an attempt to establish scaling laws. The author restricts the problem to find the method of estimation from a model test to its prototype. So, the hydrodynamic similarities such as the cavitation number and the load distribution along a blade are assumed to be similar between the model and its prototype. Also the working fluid is assumed same in both cases. Then there is no scaling effect on the fluid property. The problem is reduced to how to estimate the depth of erosion of the prototype from that of model where the flow condition and the property of the material are known. First an empirical formula which is based on experiments will be proposed, then a more complicated analysis will be presented where a modeling of mechanism of cavitation erosion will be made.
