Flow-induced vibration (FIV) is widely encountered in many scientific and engineering applications, such as aerospace, coastal, offshore, and petroleum engineering. On the one hand, vigorous FIV can potentially result in structural damage or even failure of the structure, and major economic losses, such that a variety of vibration suppression methods have been proposed and evaluated in the past decades, including active and passive controls.

A galloping fluid-instability phenomenon is commonly encountered when the control devices are implemented on the vibrating structure, altering the axis symmetry of the bluff body and hence affecting the vibration suppression efficiency. On the other hand, the vibration response is of great benefit to the concept of hydrokinetic energy harvesting, that can extract the mechanical energy of structural vibration induced by flows. To enhance the energy harvesting efficiency, large-scale arrayed harvesters are necessary, yielding a series of challenging issues, such as coupling of vibration and energy harnessing, the coupling of vibration and rotation, and wake interference and wake-induced vibration among multiple cylinders arranged in specific configurations.

The proposed aim of this Special Issue is to present current state-of-the-art research in the field of flow induced vibration, including internal single-phase or multi-phase flow induced vibration, external vortex induced vibration and rotation, wake interference and wake-induced vibration, passive and active control of vibration, and energy harvesting from flow-induced vibration, addressing a variety of topics in modelling, experiments, and applications. We welcome original research articles including in-depth research discussions, clearly identifying the current progress and challenges in the respective field. Review articles summarising the state-of-the-art progress and a thorough understanding of a particular topic in the flow-induced vibration field are also welcome.

Potential topics include but are not limited to the following:

• Flow induced vibration of rigid and flexible bluff bodies
• Multiphase flow-induced vibration
• Vortex-induced motion of floating body
• Passive and active controls of vortex shedding and vortex induced vibration of bluff bodies
• Wake-induced vibration
• Wake/proximity interference among multiple bodies
• Vortex-induced rotation of bluff bodies
• Energy harvesting based on flow-induced vibration
• Energy harvesting based on vortex-induced rotation
