Abstract : In the report, six scaling laws are derived and used to investigate the feasibility of modeling cavitation erosion. The velocity scale and size scale are studied with regard to six nondimensional ratios, namely. the erosion number, the relative nuclei size, the Weber number, the cavitation number, the cavitation inception number and the degree of cavitation. These scaling laws indicate that it is possible to model erosion in the laboratory and to predict the prototype performance. In addition, these scaling laws may be used to explain many currently available experimental observations.
