Recent studies of passive and active flow control devices for suppressing vortex-induced
vibration (VIV) of circular cylinders are reviewed extensively. The passive control devices …

Fluid flow around a circular cylinder is ubiquitous in nature and in various industrial
applications. The periodic von Kármán vortex shedding from the cylinder is one of the …

This paper focuses on the active flow control of a computational fluid dynamics simulation
over a range of Reynolds numbers using deep reinforcement learning (DRL). More …

The tandem two-cylinder configuration is frequently employed in engineering structures. Its
fluid force and vortex shedding are significantly greater than those of widely studied single …

We demonstrate the use of high-fidelity computational fluid dynamics simulations in machine-
learning based active flow control. More specifically, for the first time, we adopt the genetic …

Highlights• 91% reduction in vibration amplitude can be obtained by a flexible plate.•
Galloping is excited by a rigid plate.• The plate vibration is coupled with the flow field and …

A circular cylinder attached by a rigid splitter plate of different lengths was tested to examine
its effects on the control of flow-induced vibration. Tests were carried out in a closed-loop …

A numerical investigation was conducted to assess the effectiveness of an active control
method using a pair of air jets positioned at the two shoulders of a circular cylinder for vortex …

This study investigates the suppression mechanism of instabilities induced by fluid–structure
interactions (FSI) using passive vibration absorption devices, such as nonlinear energy sink …

Submerged floating tunnels (SFTs) offer many advantages over bridges and immersed
tunnels, and they are regarded as the most promising form of architecture for future …
