Abstract

Methods and systems provide a simulation of cavitation damage. In one implementation, a computer-implemented method (400) simulates a potential for cavitation damage. According to the method, data defining a modeled component is imported to a flow solver tool (420). The flow solver tool simulates a liquid that flows through the modeled component. Voids created by the flow of the liquid cause a plurality of vapor implosion pressure events (440). The method further includes displaying a histogram showing a portion of the modeled component. On the histogram, locations of the plurality of vapor implosion pressure events are visually distinguishable on a surface of the portion of the modeled component (450).
