摘　　要：通过对100QJ 3.2型高速深井离心泵在不同网格数、不同湍流模型、不同模拟级数条件下进行三维定常数值模拟,分析了不同条件对其性能的影响,从而选出合适的数值模拟设置方法。将性能预测结果与样机试验结果对比,验证利用CFX软件预测高速深井离心泵性能的可行性。结果表明:采用叶轮网格数为40万、Standard k-ε湍流模型、两级全流场模型对高速深井离心泵进行全流场三维定常数值模拟最为合适。In order to analysis the effect of different numerical simulation setting methods on the high-speed deep-well centrifu-gal pump performance,the three-dimensional steady numerical simulation was carried out by using different grid numbers,different turbulence models,and different simulation stages based on the 100QJ 3.2 model pump.Therefore,the best methods of numerical simulation for high-speed deep-well centrifugal pump were selected out.The comparison between numerical simulation result and the experimental result was conducted to verify the feasibility of using CFX software to predict the high-speed deep-well centrifugal pump performance.The results show that：using impeller grid number 400000,Standard k -εturbulence model,and two stages whole flow field model to predict the high-speed deep-well centrifugal pump performance is most appropriate.
