Bioinspired devices have been studied for their use in passive flow control. A hair-structure microfiber coating is studied as one such bio-inspired device. Key parameters of the microfiber coating are its length and the orientation of the hair structure. The relationship between length and angle of these fibers in a coating created through electrostatic flocking is studied herein. It is found that over 60 % of microfibers can be controlled to be aligned within 60° to 90° of the azimuthal angle regardless of microfiber length.

用于控制流量的超细纤维涂层：对取向控制中超细纤维长度的影响

已经研究了受生物启发的设备在被动流量控制中的应用。头发结构微纤维涂层被研究为一种这样的生物启发装置。微纤维涂层的关键参数是其长度和头发结构的方向。本文研究了通过静电植绒形成的涂层中这些纤维的长度和角度之间的关系。已经发现，不管微纤维的长度如何，都可以控制超过60％的微纤维在方位角的60°至90°范围内对齐。
