| 摘 要： | 湖流是湖泊中污染物扩散、悬浮物沉降及输移等的主要水动力学要素。造成湖水运动的成因机制很复杂，其中风生流是重要形式。通过应用无结构网格有限体积法sher格式的二维水流数值模型，对不同风情下的典型城市型湖泊——南京市玄武湖湖流流态进行模拟研究，探讨其吞吐流较小，沿岸无人流的情况下的风生流特征。

| Abstract: | Lake current is a main dynamic factor in pollutant diffusion, suspension load sediment and transportation etc. The mechanism of water generation in lakes is very complex. The wind driven current is an important style of lake current. Under the framework of finite volume method, Osher scheme of approximate Riemann slovers is employed in a depth-averaged 2D flow-water model. The model is used to study the Xuan Wu lake current in Nanjing city when the discharge is small and the gates around the lake are closed during the dry season. |
