| 摘 要： | 从Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程出发，采用层流模型描述水流动状态，并在欧拉坐标系中用速度－压力修正法对模型进行求解，考虑到转轮内流道几何形状比较复杂，故采用有限元法进行数值离散，并将该解法用ＦＯＲＴＲＡＮ语言编制计算程序，对三峡工程混 式水轮机转轮内部的流场进行数值计算，分析了转轮内的速度和压力分布。

| Abstract: | Beginning with Navier-Stokes equations, the flow field is described in laminar-flowmodel which is solved by SIMPLE method in Euler coordinate system. Considering the compli-cated boundary conditions of blades, the finite element method is used in flow analysis. Theprocedure is programmed with FORTRAN language. The flow field in the impeller of theSanxia hydraulic turbine with mixed flow is numerically simulated to get the distributions of ve-locity and pressure in the impeller, |
