...Xing Xie; Zhenlin Li; Baoshan Zhu; Hong Wang Purpose This study aims to complete the optimization design of a centrifugal impeller with both high aerodynamic efficiency and good structural machinability. Design/methodology/approach First, the design parameters were derived from the blade...

... is just and feasible for the case of viscous fluid flow in impellers with tip gap. Design/methodology/approach A series of steady, three‐dimensional, noncavitating and cavitating, turbulent, incompressible flows of water through two axial‐flow pump impellers were calculated by using CFD code Fluent...
