The occurrence and development of centrifugal pump rotating stall is closely related to disturbance in the incoming flow. seal clearance leakage an inherent impeller flow pumps. In order investigate influence on characteristics, field numerical simulation a under conditions with without are carried out. It found that 0.4Q0 condition leakage, “λ” special shaped high-velocity region distribution along blade leading edges strengthened, which lead larger scale vortices. And periodicity...
