Systematic model tests were conducted in a water tunnel to optimize the configuration of gate slots. Main parameters affecting cavitation inception were studied, such as the ratio of width to depth, relative offset, the slope of side wall, as well as the radius of curvature of slot's corner. The scale effects of cavitation modelling were preliminarily verified. The conformity between model studies and prototype inspections is quite agreeable. Conclusion and suggestion were made to meet the demand of hydraulic design of gate slots.展开更多
