相干管状涡在湍流中普遍存在,在湍流动力学中起着核心作用。由于许多旋涡在湍流中随机地运动,所以用肉眼不容易跟踪某一特定的旋涡。在这里,我们提出了一个自动跟踪计划的低压涡,这可能是有用的,在调查的动力学和生命历史的个别涡。
The coherent tubular vortices, which exist ubiquitously in turbulent flows and play central roles in turbulence dynamics, are visualized by the low-pressure vortices. Since many vortices move about randomly in a turbulent flow, it is not easy to track, by the naked eye, a particular vortex. Here we propose an automatic tracking scheme for low-pressure vortices which may be useful in investigating the dynamics and life history of individual vortices.
