| 摘 要： | 将喇叭管和开散式进水池内的流场视为一个整体，采用文献3]介绍的直接求解雷诺平均N-S方程和标准K-ε紊流模型方程组的方法，模拟了进水池和喇叭管内的流动，并在此基础上对喇叭管的形状进行了水力优化计算。

| Abstract: | The shape of a bellmouth has important influence on the flow pattern at the inlet sectition of the impeller chamber. The method of numerical computation for the inflow field illustrated in reference 3] is applied to simulate the flow field in pump stmp and bellmouth with which bellmouth design is hydraulically optimized. |
