由于使用了数千个点涡和较小的空间网格，获得了前缘涡层小涡配对出现的较大的离散涡，模拟了紧卷涡层的不稳定现象。
By using several thousands of point vortices and small space mesh , we obtain the large scale discrete vortices on the vortex sheet as result of the pairing of small point vortices , thus simulate the instability phenomena of the rolling-up vortex sheet .
