| 摘 要： | 首先改进了ＴＧＦＥ的基本假设考虑前后时间步之间的非线性效应，对流函数－涡量方程进行有限元离散，得到了修正Ｔａｙｌｏｒ－Ｇａｌｅｒｋｉｎ算法的有限元离散公式。采用这种方法，我们计算了后台阶绕流流动。另外，还用本方法的思想计算了叶轮机内部准三元流动。 |

| Abstract: | In this paper, the authors firstly improved one of the basic hypotheses of the Taylor-Galerkin FEM, then considered the nonlinear influence between two successive time steps and made FEM discretization of the strem function-vortex equation and then obtained the FEM discretization formula with revised Taylor-Galerkin algorithm. In this way, we computated the back step flow. In addition, we also computed the quasi three dimensional flow field in turbine machine. |
