Abstract：
Flexible slender structures are ubiquitous in biological systems and engineering applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such structures immersed in fluids. Here, we survey recent studies on highly simplified bio-inspired models (either mathematical or mechanical) that aim to revealthe flow physics associated with FSI. Various models from different sources of biological inspiration are included, namely flexible flapping foil inspired by fish and insects, deformable membrane inspired by jellyfish and cephalopods, beating filaments inspired by flagella and cilia of microorganisms, and flexible wall-mounted filaments inspired by terrestrial and aquatic plants. Suggestions on directions for future research are also provided.
摘要：
柔性细长结构在生物系统和工程应用中无处不在。流体-结构相互作用（FSI）在浸入流体中的此类结构的动力学中起着关键作用。这里,我们调查了最近对高度简化的生物启发模型（数学或机械）的研究，旨在揭示与FSI相关的流动物理学。包括来自不同生物灵感来源的各种模型，即受鱼类和昆虫启发的柔性拍打箔，受水母和头足类动物启发的可变形膜，受到微生物鞭毛和纤毛启发的细丝跳动，和灵活的壁挂式细丝灵感来自陆生和水生植物。并对今后的研究方向提出了建议。
