| 摘 要： | 本文介绍了求解涡轮机械流场的有限元法,在简化为轴对称流动的假设下,基于周向平均流面,应用流函数把涡轮机内的流动简化为二元准调和方程的描述,利用伽略金法求解各个基本方程,得到流场解。

| Abstract: | This paper presents a finite element method for solving turbomachinery flowfield problems.Under the assumption of simplification to an axisymmetric flowand on the basis of a peripheral avarage stream surface,the flow field in aturbomachine can be represented through simplification by using a slow functionto a two-dimensional quasi-harmonic equation.By use of Galerkin method,various basic equations can be solved to obtain the flow field solution. |
