摘要
In this research,a parametric control method of blade leading-edge geometry is proposed for a centrifugal pump based on previous study.Based on reasonable blade deconstruction scheme,the method adopts the change rate of leadingedge ellipse ratio from impeller shroud to hub(RaLE),the initial blade thickness(Y0)and thickness diffusion rate(Rt)as three control parameters for the blade leadingedge.The research method of combining theoretical analysis,experimental data and numerical simulation is adopted.The research indicated that according to the operating condition of centrifugal pump,the reasonable design of blade leading-edge ellipse ratio can improve its cavitation performance.This research not only proposed an effective and feasible parameter control method,but also laid a theoretical foundation for improving the inception cavitation performance of centrifugal pump through effective design.
