摘要： A method (100) is provided for predicting the likelihood of cavitation damage occurring on a surface (14a) of a hydrodynamic component (10). The method may include creating (102) 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 (103) 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 (104) 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. The method may also include analyzing (105) at least one of 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 to predict the likelihood of cavitation damage occurring at the selected surface location.

摘要： A common rail fuel system (10, 110) includes a reverse flow check valve (60, 160) fluidly positioned between each of a plurality of common rail fuel injectors (40) and an outlet (22, 154) of a high pressure pump (20). The reverse flow check valves (60, 160) divide the overall system fluid volume (80) into an upstream common volume (82) and a plurality of separate downstream volumes (83). The upstream common volume (82) is greater than the sum of the separate downstream volumes (83). The reverse flow check valve (60, 160) is movable between a first configuration with a large flow area (68, 168) and a second configuration with a small flow area (69, 169). The reverse flow check valve (60, 160) associated with each of the individual fuel injectors may be housed in a quill (50) that fluidly connects the fuel injectors to the high pressure common rail (30, 130).
