Abstract: In consideration of the action of centrifugal force, a method to analyze solid liquid two-phase fluid viscous flow on vane surface is given. As an example of real pump, the influence of vane curve on dynamic properties is analyzed and explained in theory, and is proved by contrast tests. It is clear that the influence has mainly three aspects, hydraulic efficiency, dynamic properties and theoretical delivery lift. The results give evaluated evidence of vane curve and require a method of rational vane curve. The conclusion has direct significance to typify and design of vane curve of solid liquid two-phase flow centrifugal pump in lower rotating rate.

Key words: Centrifugal pump of liquid-solid two-phase fluid  Boundary layer of two-phase fluids  Separation of boundary layer  Dynamic properties  Contrast test
