Abstract: This effect of vane shape on
centrifugal pump performance are studied. The load on vane
surface caused the generation of secondary flow within impeller,
which, in turn, has the great effect on the development of
boundary layer on suction surface at exit and therefore on the
pump performance. These should be taken into consideration in
the pump design.
Key words:
