TL;DR: In this paper, a hybrid piezoelectric wind energy scavenger with different cross-sectioned bluff bodies is presented to enhance the energy scavenging performance by coupling both the vortex-induced vibrations (VIV) and galloping phenomena.
Journal ArticleDOI
A hybrid piezo-dielectric wind energy harvester for high-performance vortex-induced vibration energy harvesting
TL;DR: In this article, a hybrid piezo-dielectric (PD) wind energy harvester was proposed to efficiently harvest the vortex-induced vibration (VIV) energy from low-speed wind.
Journal ArticleDOI
On the use of metasurface for Vortex-Induced vibration suppression or energy harvesting
TL;DR: In this paper, the authors explored the use of metasurface in designing an aerodynamic system for potential vortex-induced vibration suppression or energy harvesting, and found that the presence of meta-surface patterns has a significant influence on the aerodynamic characteristics of the bluff body.

Journal ArticleDOI
Vortex Dynamics in the Cylinder Wake
TL;DR: A review of wake vortex dynamics can be found in this article, with a focus on the three-dimensional aspects of nominally two-dimensional wake flows, as well as the discovery of several new phenomena in wakes.
Journal ArticleDOI
Vortex-induced vibrations
TL;DR: In this paper, a review summarizes fundamental results and discoveries concerning vortex-induced vibration (VIV) that have been made over the last two decades, many of which are related to the push to explore very low mass and damping, and to new computational and experimental techniques that were hitherto not available.
DissertationDOI
On the development of turbulent wakes from vortex streets
TL;DR: In this article, the authors investigated the wake development behind circular cylinders at Reynolds numbers from 40 to 10,000 in a low-speed wind tunnel and found that in the stable range the vortex street has a periodic spanwise structure.
Journal ArticleDOI
Motions, forces and mode transitions in vortex-induced vibrations at low mass-damping
TL;DR: In this paper, the authors showed that there exist two distinct types of response in a very low mass and damping regime, depending on whether one has a low combined mass-damping parameter (low m*ζ), or a high mass-ding parameter (highm*δ).

Control of Flow Over a Bluff Body
TL;DR: In this paper, the authors present control methods for flow over a bluff body such as a circular cylinder, a 2D bluff body with a blunt trailing edge, and a sphere.
