| 摘 要： | 针对二维波浪上方飞行的非定常二维地效翼进行了非线性分析．通过对二维奇点在规则波上方运动的Green函数的推导，利用离散涡方法解决了二维波浪上方飞行的非定常地效翼的升力问题．针对不同的几何参数和波浪参数对升力系数进行了研究．通过与定常情况的对比，验证了方法的有效性.

| Abstract: | A nonlinear analysis on a 2D foil subject to wing-in-ground effect (WIG) operating above water waves was made. Through the derivation of the Green’s function for 2D singularities moving above regular water waves, the 2D lifting problem for a foil above water waves was addressed using the discrete vortex method. The results of non-dimensional lift coefficient were presented with the variation of different geometry and water wave parameters. The existing steady data are utilized to validate the present study. |
