| 摘 要： | 基于SIMPLE-C算法，对力堵塞泵的内部三维不可压湍流流动进行了数值模拟．在计算过程中采用雷诺时均N-S方程和修正了的k-ε湍流模型，计算在贴体坐标系和交错网格中进行，从而揭示出无堵塞内湍流流动的速度分布、压力分布规律，及其湍动能分布规律，并对无堵塞泵进行了性能预测，根据实验结果对其结构进行了优化．

| Abstract: | The 3-D turbulent flow in Non-clogging pump is simulated. The time-averaged N-S equations and the k - εturbulent model is modified The calculation is carried out in Body-fitted Coordinated grid by applying SIMPLE-C algorithm. The calculated velocity, pressure distributions of the turbulent flow in the Non-clogging pump are obtained, which will be helpful for the optimal design and performance prediction of Non-clogging pump on the basis of flow field simulation. |
