流动控制是试图有利地改变流场的特性，而不是流沿表面沿着自然发展。天生的飞行者和游泳者利用气流控制来在不同的飞行和环境条件下保持机动性和效率。在这里，我们回顾了鸟类，昆虫和水生动物的流量控制策略，以及受其启发的工程系统。我们主要集中在被动和本地流量控制设备，具有实用程序的小型无人机和水上交通工具（sUAV）的好处，如简单和降低功耗。我们还确定了与生物流量控制的物理学相关的研究差距，以及在工程车辆上开发和实施设备的机会。
Flow control is the attempt to favorably modify a flow field’s characteristics compared to how the flow would have developed naturally along the surface. Natural flyers and swimmers exploit flow control to maintain maneuverability and efficiency under different flight and environmental conditions. Here, we review flow control strategies in birds, insects, and aquatic animals, as well as the engineered systems inspired by them. We focus mainly on passive and local flow control devices which have utility for application in small uncrewed aerial and aquatic vehicles (sUAVs) with benefits such as simplicity and reduced power consumption. We also identify research gaps related to the physics of the biological flow control and opportunities for device development and implementation on engineered vehicles.
