| 摘 要： | 本文给出了一种求解多段翼型位流的高阶面元法。面元和奇点的分布分别采用了二阶和三阶的形式。由于高阶面元法较为精确地反映了绕流体的几何形状和奇点表面分布,本文给出了比低阶面元法更为精确的解,并且消除了低阶面元法计算中经常出现的翼型后缘处解的波动。

| Abstract: | A high-order panel method is presented for calculating of potential flow around multi-element airfoils in this paper. The method is based on the second-order or third-order geometric panel and vortex singularities. Because the high order formulation can match the singularities and represent the configuration of airfoils adequately, it can give accurate solution of potential flows. It is also shown that poor trailing-edge solutions associated with low-order panel methods do not appear for the present method. |
