| 摘 要： | 对双流道泵叶轮内三维不可压湍流流动进行了数值模拟。计算采用了雷诺时均N-S方程和修正了的k-ε湍流模型，计算在体贴坐标系和交错网格中进行并采用了SIMPLE-C算法。计算结果揭示了双流道泵叶轮内湍流流动的压力分布和速度分布规律。研究结果可以用来对双流道泵进行性能预测并为双流道泵的优化设计创造了条件。

| Abstract: | The 3-d turbulent flow in the impellers of double-channel pump issimulated in this paper. By using the time-averaged N-S equations and the k-eturbulent model modified to consider the curvature and rotation, applying SIMPLE-Calgorithm to make pressure-velocity correction equation, the calculation is carriedout with Body-fitted Coordinated grid. The calculated velocity and pressuredistributions of the turbulent flow in double-channel pumps are given for the firsttime, which will be supportive to the optimal design and performance prediction ofdouble-channel pumps on the basis of flow field simulation. |
