Numerical Modelization of the Flow in Centrifugal Pump: Volute Influence in Velocity and Pressure Fields
A 3D-CFD simulation of the impeller and volute of a centrifugal pump has been performed using CFX codes. The pump has a specific speed of 32 (metric units) and an outside impeller diameter of 400 mm. First, a 3D flow simulation for the impeller with a structured grid is presented. A sensitivity anal...

| description | A 3D-CFD simulation of the impeller and volute of a
centrifugal pump has been performed using CFX codes. The pump has
a specific speed of 32 (metric units) and an outside impeller
diameter of 400 mm. First, a 3D flow simulation for the
impeller with a structured grid is presented. A sensitivity
analysis regarding grid quality and turbulence models were also
performed. The final impeller model obtained was used for a 3D
quasi-unsteady flow simulation of the impeller-volute stage. A
procedure for designing the volute, the nonstructured grid
generation in the volute, and the interface flow passage between
the impeller and volute are discussed. This flow simulation was
carried out for several impeller blades and volute tongue relative
positions. As a result, velocity and pressure field were
calculated for different flow rates, allowing to obtain the radial
thrust on the pump shaft. |
