关于欧拉方程盘状涡斑中粒子轨迹的卷绕数

On the winding number for particle trajectories in a disk-like vortex patch of the Euler equations

Kyudong Choi, In-Jee Jeong

摘要:

我们考虑不可压缩欧拉方程的涡补丁解决方案在平面上。结果表明,当初始斑块足够接近圆盘时,斑块中大多数粒子绕原点的卷绕数随时间线性增长。

英文摘要:

We consider vortex patch solutions of the incompressible Euler equations in the plane. It is shown that the winding number around the origin for most particles in the patch grows linearly in time when the initial patch is close to a disk enough.
