Interactions between fluid flow and elastic structures are important in many naturally occurring and engineered systems. This review collects and organizes recent theoretical and experimental developments in understanding fluid-structure interactions at low Reynolds numbers. Particular attention is given to the motion of objects moving in close proximity to deformable soft materials and the ensuing interplay between fluid flow and elastic deformation. We discuss how this interplay can be understood in terms of forces and torques, and harnessed in applications such as microrheometry, tribology, and soft robotics. We then discuss the interaction of soft and wet objects close to contact, where intermolecular forces and surface roughness effects become important and are sources of complexity and opportunity.

低雷诺数时接触附近的流体-弹性相互作用


流体流动和弹性结构之间的相互作用在许多自然形成和工程系统中非常重要。本综述收集并组织了理解低雷诺数固耦合的最新理论和实验进展。特别注意在可变形软材料附近移动的物体的运动，以及随之而来的流体流动和弹性变形之间的相互作用。我们讨论了如何从力和扭矩的角度来理解这种相互作用，以及如何在微流变测量、摩擦学和软机器人等应用中加以利用。然后，我们讨论了靠近接触的软物体和湿物体的相互作用，其中分子间作用力和表面粗糙度效应变得很重要，是复杂性和机会的来源。
