NUMERICAL SIMULATION OF INTERNAL FLOW WITHIN PUMP AND PUMP ARRANGEMENT

摘要

Based on the standard k-ε turbulent model and the Reynolds-Averaged Navier-Stokes equations, the finite volume method and the SIMPLE algorithm were adopted to carry out the three-dimensional numerical simulation of the internal flow within pump arrangement and multiform pumps in double reference frames. According to the comparison of the results of the numerical simulation and the experimental data, the CFD technique applied to the performance prediction in pump and pump arrangement have a quite credibility in a certain range, however, in order to simulate more accurately the internal flow within the pumps and predict precisely the full performance, profound researches should be done.
