Abstract
A method is provided for predicting the likelihood of cavitation damage occurring on a surface of a hydrodynamic component. The method may include creating a computational fluid dynamics (CFD) simulation of the hydrodynamic component, wherein creating the CFD simulation includes simulating fluid flowing relative to the hydrodynamic component. The method may also include selecting a location on the surface of the hydrodynamic component, wherein the selected location is exposed to the simulated fluid flow. The method may also include determining and analyzing at least one of a mean pressure and standard deviation, a standard deviation of the rate of change in pressure, a mean void percentage and standard deviation, and a standard deviation of the rate of change in void percentage for the flowing fluid at the selected surface location to predict the likelihood of cavitation damage occurring at the selected surface location.
