Numerical Studies of Abrasion Wear on the Guide Vanes in a Submersible Axial Flow Pump

摘要

The paper presents the numerical studies of abrasion wear on the guide vanes in a submersible axial flow using OpenFOAM code, which is an Open Source CFD Package. Hashish erosion model was implemented in this code. The 3-D turbulent particulate-liquid two-phase flow equations are employed in this study. The computing domain is discretized with a full three-dimensional mesh system of unstructured tetrahedral shapes. The finite volume method is used to solve the governing equations and the pressure-velocity coupling is handled via a Pressure Implicit with Splitting of Operators (PISO) procedure. Simulation results have shown that the sand erosion rate on pressure side is more than on the suction side of the guide vanes. The abrasion wear occurs mainly at the lower part of the guide vanes.
