摘要
采用九节点四边形等参元函数实现局部坐标变换 ,采用二阶精度的MacCormack格式离散求解变换后的水流控制方程 ,建立了一种平面二维数学模型
A two dimensional mathematical model is established by using a local coordinate system adopting a nine sectional point quadrangle and by using the two order accuracy MacCormack scheme of water controlling equations. This mathematical model can effectively calculate the velocity field of the complex borders of the river.
