Internal Flow Field Simulation of Screw Centrifugal Pump with Double Blades

The standard k-e turbulence model and CFD software are applied to analyze the internal flow field of the screw centrifugal pump with double blades by FLUENT.Through analyzing the important performance like internal velocity,pressure distribution flow impacts and clearance flow and so on,it supplies reliable measures to improve the pump's performance and meliorate the pump and it provides great bases to design the screw centrifugal pump with double blades.
