【摘要】 从二维浅水非恒定流的控制方程出发 ,建立了一个二维湖泊流体动力学模型。并根据天津于桥水库的实际情况 ,对该水库引水期和非引水期的湖水流场的不同情况进行了模拟试验。结果表明 ,在引水期水库的流场达到稳定状态时 ,水库流场有一个自东向西的水流主要通道。还对水库出口处有初始水体流速的情况进行了模拟。模拟的结果与于桥水库的实际污染物浓度分布基本一致。更多还原

【Abstract】 Based on the two-dimension adlittoral non-invariablenes flow control equation of lakes,a hydrodynamic model of lakes was built up.According to the real situation of Tianjin Yuqiao Reservoir,the model simulated the stream fields for import water period and no-import period.The simulated results indicate that when the stream field begins steady,there is a steady main flow channel from the east part of the lake to the west part.The simulation with initial out flow velocity has been done and the simulation results show that the stream fields have a good relationship with the pollutants distribution.更多还原
