Abstract

Natural organisms have evolved numerous functional surfaces and structures on their body surfaces over billions of years of evolution, which have shown excellent drag reduction effects in a wide range of applications. From a biomimicry perspective, techniques for reducing drag, such as compliant walls, superhydrophobic surfaces, and surface textures, originate from the features of living things in the natural world. These techniques, which are important for sustainable development, can increase productivity, cut down on energy loss, preserve the environment, and be applied to industrial production, sports, transportation, and other areas. This paper presents systematic elaboration of the structure or properties of functional surfaces from the standpoint of typical biological characteristics. Additionally, a summary of bionic drag reduction techniques, guiding principles, and related research findings is provided, which can serve as a resource for both further study and real-world implementation.

仿生界面减阻方法及原理综述
在数十亿年的进化过程中,自然生物在其身体表面进化出了许多功能表面和结构,这些表面和结构在广泛的应用中显示出优异的减阻效果。从仿生学的角度来看,减少阻力的技术,如柔顺壁、超疏水表面和表面纹理,源于自然界生物的特征。这些技术对可持续发展很重要,可以提高生产力,减少能源损失,保护环境,并可应用于工业生产、体育、运输和其他领域。本文从典型生物学特性的角度系统阐述了功能表面的结构或性质。此外,对仿生减阻技术、指导原则和相关研究成果进行了总结,为进一步研究和实际应用提供了参考。
