Abstract

Fluid-induced vibrations in flags provide unattended, efficient, low-cost, and scalable solutions for energy harvesting to power distributed wireless sensor nodes, heat transfer enhancement in channel flow, and mixing enhancement in process industries. This review surveys three representative mechanisms of fluid-induced vibrations, namely, instability-induced excitation (IIE) of an inverted flag due to fluid flow, movement-induced excitation (MIE) in a conventional flag, and extraneously induced excitation (EIE) of a flag behind a bluff body. Their instability boundaries, vibration dynamics, and vortex dynamics are compared in a unified framework to elucidate the distinct features of various fluid-induced vibrations and provide insights into the design of vibrating flags for various applications. Some common features are identified and analyzed for describing the interaction between multiple flags, three-dimensional effects, and Reynolds number effects. The suggestions are intended to guide future research directions.
