本文用数值方法求解了一对反向旋转的点涡在自身影响下向自由面上升的非线性二维自由面势流问题。这两个涡流被插入到最初静止的流体中。边界/积分方程法是用来获得自由表面的海拔和流线的几个涡强度的上升对涡。将这两个涡的路径与刚性壁面下的反向旋转涡对的路径进行了比较。
The problem of calculating nonlinear two-dimensional free-surface potential flow about a pair of counter-rotating point vortices rising under their own influence towards a free surface is solved numerically. The two vortices are inserted into fluid which is initially at rest. A boundary/integral-equation method is used to obtain free-surface elevations and streamlines about the rising pair of vortices for several vortex strengths. The paths of the two vortices are compared with those of a counter-rotating vortex pair under a rigid wall.
