Abstract:
In this work, the numerical investigation of the complex liquid flow in a centrifugal pump modelconsisting of an impeller, a diffuser and a volute was done to analyze the effects that the blade height, the diffuser blade number, and the volute size had on the pump performance. The continuity and Navier-Stokes equations with the k- turbulence model and the standard wall functions based on the logarithmic law were used by mean of ANSYS-CFX code. The results achieved reveal that the selected key design parameters have an impact on the pump head, the brake horsepower and the overall efficiency.
