| 摘 要： | 本文对于二维不可压无旋流问题,采用了Galerkin法求数值解。文中分别选速度势和流函数作为试函数。本文同时给出了用直接配点法和最小二乘配点法的计算结果,并将这些结果与T.J.Chung《Finite Element in Fluid Dynamics》一文中C=∞时的半解析解进行了比较。计算中采用Simpson积分子程序和Gauss消元法。

| Abstract: | In this paper, Galerkin method is used to solve the problem of two-dimensional imeompressihle irrotational flow. The velocity potential and stream function are selected as trial functions. In the meantime, comparative studies are made, between the results of this and least-square collocation method and the half-analytical solution when c=given in "Finite Element in Fluid Dynemics" |
