A highly efficient mixed flow pump can prevent flow separation which is likely to occur in a corner portion of a flow passage of a diffuser section. The mixed flow pump includes a casing having an axis and defining an impeller section and a diffuser section disposed downstream of the impeller section with stationary diffuser blades protruding from a hub. The diffuser blades are formed so that an angular difference, between a hub blade angle and a casing blade angle, is chosen to conform to a specific distribution pattern along a flow passage of the diffuser section.

Mixed flow pump

Disclosed is an impeller for a turbomachine. The impeller comprises a hub, full blades equidistantly disposed on the hub in a circumferential direction, and a splitter blade disposed between each adjacent two of the full blades. The splitter blade is shaped in such a way that a spanwise distribution of a pitchwise position of a leading edge of the splitter blade is determined according to a spanwise and pitchwise non-uniformity distribution of fluid velocity of a fluid flowing into the splitter blade, whereby a non-dimensional circumferential position of a leading edge of the splitter blade varies in a spanwise direction.
