Abstract
Meshing is an important preprocessing part of numerical simulation for water pump, which has important influence on numerical results. In order to simulate internal flow field in water pump more accurately, three different types of grids with hexahedron, polyhedron and tetrahedron are applied to simulate the internal flow field of impeller by using improved k-ω SST turbulence model. Besides, simulating results are compared with PIV testing results by evaluating their accuracy. Numerical simulation results show that the proposed simulation method reduces the requirement for computer configuration. Internal flow field of the reflux pump will be captured more accurately using polyhedral meshes with improved k-ω SST turbulence model, which has a high accuracy and high computational efficiency as well as strong adaptability.
