Analysis of numerical calculation on an axial-flow pump model with 0° installation angle

The author used ANSYS CFX software to analyze an axial-flow pump model with 0° installation angle under steady and unsteady operating conditions. Based on the mesh independence research,the suitable hexahedral mesh number was used for the standard k- e model with scalable wall function. The difference between numerical simulation and experimental result was compared and analyzed. This work is of real significance in understanding accuracy of numerical simulation for axial-flow pump.
