近年来,射流弹球被认为是探索机器学习流体流动控制的一种有吸引力的、有效的流动结构。在这篇文章中,我们重点研究了当雷诺数平滑增加时,该系统在无激励的情况下通向混沌的路径。发现它是Newhouse-Ruelle-Takens类型的,有一个二次干叉分叉,打破了平均流场的对称性,使其进入准周期。
The fluidic pinball has been recently proposed as an attractive and effective flow configuration for exploring machine learning fluid flow control. In this contribution, we focus on the route to chaos in this system without actuation, as the Reynolds number is smoothly increased. It was found to be of the Newhouse-Ruelle-Takens kind, with a secondary pitchfork bifurcation that breaks the symmetry of the mean flow field on the route to quasi-periodicity.
