降低瓜渚湖出口水位增加水体流动二维数值研究

2-D Numerical Investigation of Water Flow Promoting in Guazhu Lake Outlets

利用二维数学模型计算研究了在出口水位降低10 cm其他条件不变的控制条件下湖泊水域内水体流动,定量分析了降低瓜渚湖出口水位、增加流入和流出瓜渚湖水域水位差,以及对瓜渚湖水域流速和瓜渚湖水动力的影响,结果表明,瓜渚湖内水流运动流速增加明显,增加速度在1~12倍,个别时刻和位置流速增加更多.

Based on the 2-dimensional mathematical model, the water flow in certain water area is studied with the water level 10cm lower, and the quantitative analysis on waterhead in Guazhu Lake is also conducted by lowering the water level, and increasing the inflow and outflow, and its influence on flow velocity and hydrodynamic force is also observed. The resuits shows that the water velocity in Guazhu Lake increased significantly, with the speed of 1 - 12 times, in special locations or periods, the velocity increases even more.
