Abstract

The study of a flexible body immersed in a flowing medium is one of the best way to find its aerodynamic shape. This Letter revisited the problem that was first studied by Alben et al. (Nature 420, 479–481, 2002). To determine the aerodynamic shape of the fibre, a simpler approach is proposed. A universal drag scaling law is obtained and the universality of the Alben-Shelley-Zhang scaling law is confirmed by using dimensional analysis. A complete Maple code is provided for finding aerodynamic shape of the fibre in the flowing medium.

柔性纤维在流动介质中的气动外形及阻力标度规律

研究浸入流动介质中的柔性物体是找到其空气动力学形状的最佳方法之一。这封信重新审视了Alben等人首次研究的问题。（《自然》杂志420479–4812002）。为了确定纤维的空气动力学形状，提出了一种更简单的方法。得到了一个普遍的阻力标度律，并通过量纲分析证实了Alben-Shelley-Chang标度律的普遍性。提供了一个完整的Maple代码，用于寻找流动介质中纤维的空气动力学形状。
