【摘要】 针对江都三站运行存在的主要问题,采用了直接求解基于时间平均的N-S方程雷诺和k-ε紊流模型方程组的方法,通过数值模拟预测肘形弯管进水流道内部流动,优选了肘形弯管的改造方案。改善了流速分布,使得该泵站装置具有了较高的性能。更多还原

【Abstract】 A method based on numerical computations of the turbulence flow isapplied to analyze the flow field of the elbow tube of pump suction. An optimumscheme was designed. A good agreement was achieved between the calculation data andthe result of model test. The named height of elbow tube of Jiangdu No.3 PumpingStation reaches the critical value. Through optimum numerical design, the pumpingstation could works efficiently with high stability.更多还原
