Abstract
This study investigates the effects of sweep angle, blade pitch angle, and inlet angle of the propeller hub on the hydraulic characteristics of a submersible axial flow pump by using three-dimensional Reynolds-averaged Navier-Stokes equations. The shear stress transport turbulence model was used for the analysis of turbulence. The finite volume method and unstructured hexahedral grids were used in the numerical analysis. The optimal grid system in the computational domain was selected through a grid-dependency test. A performance test was conducted for the submersible axial flow pump, and their results were compared with the numerical analysis results. Effects of geometric parameters of the rotor blades on the efficiency and total head of the submersible axial-flow pump were evaluated.
