摘要

我们在此研究了螺旋结构对不对称液滴沿垂直扭曲纤维运动的影响。液滴在重力的驱动下围绕纤维束做螺旋运动。这种复杂的运动可以通过改变纤维的捻度来操控。当液滴的尺寸小于螺旋线的特征长度（螺距）时，液滴主要采用与扭曲纤维的沟槽相关的螺旋运动。当液滴尺寸超过螺距长度时，就会出现间歇性垂直滑动和螺旋运动的混合运动。一个模型描述了旋转速度和线性速度与纤维扭曲圈数的函数关系。这项研究强调了亚结构在液滴动力学中的深远作用，为液滴操纵或基于纤维的设备提供了新的见解。

Droplet Helical Motion on Twisted Fibers.

We investigate herein the impact of helical structures on the motion of asymmetrical droplets along vertically twisted fibers. The droplet adopts helical motion around the bundle driven by gravity. This complex motion can be manipulated by varying the twists turns of the fibers. When the droplet size is smaller than the characteristic length of the helix (pitch), the droplet adopts a predominant helical motion correlated to the groove of the twisted fibers. When the droplet size exceeds the pitch length, a mixed motion of intermittent vertical sliding and helical movement emerges. A model describes rotational and linear speeds as a function of the number of fiber twist turns. This research highlights the profound role of substructures in droplet dynamics, offering fresh insight into droplet manipulation or fiber-based devices.
