Abstract EN
The interflow plays important roles in centrifugal pump design.
In order to study the effect of rotation and z-axis on internal flow, two-dimensional particle image velocimetry (PIV) measurements have been performed to measure the steady velocity field on three planes in all impeller passages of a low specific-speed centrifugal pump.
The results show that the relative velocity flows in blade passages are obviously different in terms of the positions of the blade relative to the tongue.
The interaction between the impeller and tongue changes the occurrence and development of low velocity region with time.
From shroud to hub, the relative velocity gradually increases, and the minimum value moves toward the suction surface.
On the midplane, the magnitude increases with increased flow rate from pressure surface to suction surface, while at the shroud and hub, the measured velocity first increases with decreased flow rate from the blade pressure surface to nearly ζ=0.5 to 0.6.
