雨水泵站调蓄池三维数值模拟

The Three-dimensional Numerical Simulation of Furongjiang Pump Station Regulation Pool

建立调蓄池底部沟槽排沙模型,利用三维紊流数值模拟的方法,模拟了调蓄池底部沟槽在不同工况下的水流流态,特别是流道曲率变化处的流场,预测调蓄池在各个运行模式下,是否达到冲淤流速,并通过物理模型试验来论证.结论表明,数模计算与物理模型试验吻合得很好,降低了试验成本.

The paper sets up Furongjiang pump station regulation pool, uses 3 - dimension numerical simulation method to simulate the mode of regulation pool and elicit the velocity of flow at each flux, especially at the corner of the launder and forecasts if the velocity in the regulation pool reaches non - nmd filling velocity under various modes. It can be verified by physical model experiment. The results suggest that numerical simulation fits physical model experiment.
