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 …

Deep Reinforcement Learning (DRL) has recently been proposed as a methodology to
discover complex active flow control strategies [Rabault et al.,“Artificial neural networks …

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 …

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 …

The strategic implementation of local blowing (LB) around a circular cylinder within a
uniform flow has demonstrated its capacity to effectively suppress aerodynamic noise under …

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 …

We propose a novel active-flow-control strategy for bluff bodies to hide their hydrodynamic
traces, ie, strong shears and periodically shed vortices, from predators. A group of windward …

Recently, energy harvesting through periodic snapping, namely snap-through, has gained
significant attention for energy harvesting applications. In this study, the snapping dynamics …

The honeycomb-shaped structure has been proved to have good mechanical properties,
and is it possible combining its good mechanical properties together with its flow …
