摘　　要：在计算模型采用分块非结构六面体网格划分基础上,运用雷诺平均N-S方程和标准的k-ε双方程湍流模型,结合SIMPLEC算法,利用Fluent软件,对旋流泵不同叶片宽度、叶轮外径与壳体的间隙进行数值模拟,并分析其对泵扬程和效率的影响,总结出旋流泵的最佳流道参数。According to Reynolds Average N-S Equation enclosed by standard k-ε turbulence model, the numerical simulation was conducted for different sizes of vane width and gaps between the impeller outside diameter and the shell using Fluent software with the algorithm SIMPLEC on the basis of non-structural hexahedral mesh model. The influence of the parameters on the head and efficiency of the pump was analyzed, and the best flow parameters were obtained.
