摘要
为适应具有自由面的二维流动问题中流动区域不能预先给定的特点,本文应用有关y函数的理论,推导了映象平面内不可压缩理想流体关于y函数的定常流动有限元方程,并介绍了驼峰溢流堰过堰流动问题的有限元解算例。
It is impossible to know the boundary of 2-D flow field with free water surface previously. In order to suit this condition better, the theory of function Y is applied to derive finite element equation for steady flow of incompressible ideal fluid in mapping plane. And the example of finite clement computation of weir flow is given in this paper.
