| 摘 要： | 从控制方程组出发,以Galerkin有限元法为基础,引入沿流线加权的权函数(沿流线加权的迎风有限元法)和选择性集中系数矩阵方法,推导、建立了一适合于浅水湖泊风生流计算的二维迎风有限元数值模型。并以太湖为例,对模型作了检验,分析了均匀、定常风场持续作用下太湖风生流场的形态特征。

| Abstract: | Based on Galerkin finite element method, a new upwinding finite element numerical model suitable for modeling wind-driven current in shallow lakes is derived by introducing streamline-upwinding method and the selective lumping coefficient matrix scheme. Moreover it is applied to Taihu Lake, and the morphological characteristic of wind-driven current is discussed. |
