Abstract
The Navier-Stokes equations and Spalart-Allmaras turbulent model were used to numerically simulate the internal flow of a centrifugal pump with different blades and under different conditions, and the test results were compared. The results shows that within a certain range, by increasing the number of impeller’s blades, the flow stability of the fluid can be effectively improved and the high efficiency zone and the head of the pump can be greatly enhanced. This study also shows that numerical simulation can accurately predicate the complicated three-dimensional flow and the hydraulic performance of the centrifugal pump.
