摘　　要：采用直接求解雷诺平均N－S方程和标准k－ε紊流方程组的方法，模拟了方箱式双向进水流道内的流动。提出了泵站进水流道优化水力计算的目标函数。对具有不同几何线型的双向进水流道进行了比较性优化计算，求得了方箱式双向进水流道的水力设计准则。理论计算与模型试验结果较为一致。The flow in a two-way suction box is computed by means of three dimensional Reynolds-averaged Navier-Stokes equations using the standard k-ε model. Computations for the suction boxes with varied geometrical parameters were performed and compared in the light of the objective functions. Principles for the hydraulic design of two-way suction box were suggested and a good agreement was achieved between the calculated data and the result of model test.
