- W2351512452 abstract "Impeller is the vital constitution of centrifugal pump,and the design parameters of impeller will directly impact the pump's working performance.This work focused on blade outlet angle's effect on the performance of pump.Method of Bezier curve-fitting was employed to design the profile of blade.The design processes of impeller were depicted,where the profile of blade was Bezier curve.Pump performances with 11 different types of impellers,whose outlet angles are different and belong to range[20°,30°],were studied by numerical method.The simulation results indicate that the head of pump increases with the increasing outlet angle of blade.This variation trend of the head is almost consistent with the theoretical rule.Meanwhile,the relation between head of pump and outlet angle of blade,under three different flow conditions,was studied.It was found that the variation of pump efficiencies turns on a parabola in the range of the outlet angles.When the outlet angle is designed at the range[23°,24°],the pump achieves the best performance.The numerical simulation method is an important tool to optimize the design parameters of pump structure,which will facilitate the process of research and development of high efficient pumps." @default.
