  • Methods of predicting cavitation damage
    Patent number: 7912687
    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.

  • High pressure cavitation system
    Patent number: 7878052
    Abstract: The present disclosure is directed towards a clamping assembly for compressing a plurality of optical plates of a high pressure cavitation system. The clamping assembly may include a mounting frame and a housing coupled to the mounting frame. The clamping assembly may further include a holder distal the housing, the holder having the plurality of optical plates disposed therein. The clamping assembly further including a controllable clamping mechanism operably coupled to a top of the housing, the controllable clamping mechanism applying an axial force to the plurality of optical plate.

  • Methods of predicting cavitation damage
    Publication number: 20080215255
    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 a fluid proximal to the surface of 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. The method may further include determining the mean pressure and standard deviation, the standard deviation of the rate of change in pressure, the mean void percentage and standard deviation, and the standard deviation of the rate of change in void percentage for the fluid at the selected surface location.
