摘　　要：为了提升双吸离心泵的性能,研究其内部流动规律,采用RNGk-ε方程湍流模型和标准SIMPLE算法对某一扭曲叶片双吸离心泵全流道进行了CFD分析,并与实验值进行比较。结果表明,该方法能够较为准确地预测出双吸离心泵叶轮与蜗壳间及内部的流动特性,所得结果对进行双吸离心泵的水力设计或改型优化设计等研究具有重要的指导意义。In order to improve the performances of double-suction centrifugal pump and to attain the rule of inside flow field, the RNG k-ε turbulence model and the standard SIMPLE algorithm are applied to simulate the full flow passage of the double-suction centrifugal pump with twisted-blade by CFD, the results of experiment were compared. At the same time, it showed that this method could forecast main characteristics of the flow between the blade and spiral case double-suction centrifugal pump, which is of important guiding significance for the hydraulic design and improvement optimal design of double-suction centrifugal pump.
