摘要

流体流动和弹性结构之间的相互作用在许多自然发生和工程系统中都很重要。这篇综述收集和组织了最近在理解低雷诺数下流固相互作用方面的理论和实验进展。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，并在微流变学、摩擦学和软机器人等应用中加以利用。然后我们讨论靠近接触的柔软和潮湿物体的相互作用，其中分子间力和表面粗糙度效应变得重要，并且是复杂性和机会的来源。预计流体力学年度评论的最终在线出版日期，第56卷是2024年1月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

Fluid-Elastic Interactions near Contact at Low Reynolds Number

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.Expected final online publication date for the Annual Review of Fluid Mechanics, Volume 56 is January 2024.

期刊介绍： The Annual Review of Fluid Mechanics is a longstanding publication dating back to 1969 that explores noteworthy advancements in the field of fluid mechanics. Its comprehensive coverage includes various topics such as the historical and foundational aspects of fluid mechanics, non-newtonian fluids and rheology, both incompressible and compressible fluids, plasma flow, flow stability, multi-phase flows, heat and species transport, fluid flow control, combustion, turbulence, shock waves, and explosions. Recently, an important development has occurred for this journal. It has transitioned from a gated access model to an open access platform through Annual Reviews' innovative Subscribe to Open program. Consequently, all articles published in the current volume are now freely accessible to the public under a Creative Commons Attribution (CC BY) license. This new approach not only ensures broader dissemination of research in fluid mechanics but also fosters a more inclusive and collaborative scientific community.
