The authors define the energy parameter as the ratio of the volume loss of specimen material during erosion test to a certain fraction of the work done by the cavitation drag force. On the grounds of the analysis of the initial formula of the energy parameter as well as on the basis of experimental investigations, a method is suggested to allow for the influence of geometrical similarity (scale effects) upon cavitation damage when flow velocity or the characteristic dimension of the model and certain physical properties of the fluid, such as viscosity, surface tension, or density, are varied.
