| 摘 要： | 本文介绍用边界元法计算不可压缩回转面流场,并给出了S_1流面上的运动方程,采用线性单元对边界进行离散化,将库塔条件与边界元方程直接联立求解,并且较好地解决了用边界元法解回转面时所遇到的周期性边界问题。

| Abstract: | In this paper, the boundary element method (BEM) is applied to solve the flow system on blade-to-blade (B-to-B)surfaces of revolution in a turbine. Equations governing fluid flow on sl stream surfaces are derived. The linear elements are employed to discrete the boundaries. Kutta condition is a direct combination of the boundary element equation. It can also handle the period boundary condition solving the problem on B-to-B surfaces of revolution by means of BEM. |
