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。
In order to adapt to the problem that the flow area can not be predetermined in the two-dimensional flow problem with free surface, we apply the theory of y-function to derive the steady flow finite element equation about incompressible ideal fluid in y- A Finite Element Solution of Hump Overflow Weir Flow Problem.
