了解水动力相互作用在鱼类游泳中的作用可能有助于解释鱼类为什么以及如何在鱼群中游泳。在这项工作中,我们设计了控制实验,研究鱼类在扰动流中游泳。具体来说,我们记录了尾拍频率的鱼游泳的存在下,主动控制的翼型俯仰在不同的频率。我们提出了一个信息理论的方法来量化的影响,俯仰翼型运动的动物游泳。在这项工作中开发的理论框架可能会告知未来的调查机制的基础上,在群体教育。
Understanding the role of hydrodynamic interactions in fish swimming may help explain why and how fish swim in schools. In this work, we designed controlled experiments to study fish swimming in a disturbed flow. Specifically, we recorded the tail beat frequency of a fish swimming in the presence of an actively-controlled airfoil pitching at varying frequencies. We propose an information-theoretic approach to quantify the influence of the motion of the pitching airfoil on the animal swimming. The theoretical framework developed in this work may inform future investigations on the mechanisms underlying schooling in groups.
