Abstract:The internal flows of six groups of high pressure pump for 10 000 tons Reverse Osmosis Desalination System hydraulic model were simulated by FLUENT,and their performance characteristics were predicted by using Reynolds-averaged Navier-Stokes(RANS) equations,k-ε turbulence model and multi-reference frame.Two groups of high-efficiency hydraulic model were selected to combine two single-stage model pumps for test research.Comparing the prediction and test performances,the capacity- head curve is closer near the flow region with high efficiency;the error is within the permitted extent by the engineering application.The efficiency from test is lower than that from simulation,because in CFD calculation the volumetric loss and mechanical loss are not considered.The adjusted data from simulation is close to the experimental one.The test shows that the efficiency of the model pump is close to 80%.
