Abstract：Analyzing the 3D turbulent flow field in the axial pump impeller is significant for improvingproperties and optimum design level of hydro impeller. In this paper, the 3D turbulent flow is stimulated basedon Navier-Stokes equations and k-εmodel. The turbulent flow through axial pump impeller is simulated byusing the non-uniform triangle mesh system and the finite volume method. Calculated results are presented atthe design operating condition for the impeller in detail, which give a valuable reference to improve theperformance of the impeller.
