Cross-flow vortex induced vibrations of inclined helically straked circular cylinders: An experimental study
TL;DR: In this article, the results of some towing tank experiments on the vortex induced cross-flow vibrations of bare and helically straked cylinders in vertical and inclined arrangements were reported.
Journal ArticleDOI
The influence of taper ratio on vortex-induced vibration of tapered cylinders in the crossflow direction
TL;DR: In this article, a series of experiments were conducted to study vortex-induced vibration of tapered cylinders free to oscillate in the crossflow direction in a re-circulating water tunnel with an open surface test section for a Reynolds number range of Re=370-2300.

Towards an understanding of the marine fouling effects on VIV of circular cylinders: Response of cylinders with regular pyramidal roughness
TL;DR: In this article, an experimental study on the VIV of low mass-damping circular cylinders with artificial marine fouling was performed and the experimental results showed that, the peak VIV amplitude, the synchronisation range, the lift force coefficient, the mean drag coefficient and the fluctuating drag coefficient were decreased by the fouling.

Flow induced vibrations of a sharp edge square cylinder in the wake of a circular cylinder
TL;DR: In this paper, the influence of the wake of a fixed circular cylinder on the response of a downstream square cylinder at different spacing ratios (S/D ǫ = 4, 8, 11) is experimentally investigated.
Journal ArticleDOI
Numerical simulation of vortex-induced vibration of a circular cylinder in a spanwise shear flow
TL;DR: In this article, the authors investigated the vortex-induced vibration of a circular cylinder with a length-to-diameter ratio of 192 in a span-wise shear flow and found that the response amplitude for a cylinder in a uniform flow was slightly greater than that for a cylindrical cylinder in uniform flow.

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.
Journal ArticleDOI
Vortex formation in the wake of an oscillating cylinder
TL;DR: In this paper, it was shown that the acceleration of the cylinder each half cycle induces the roll-up of the two shear layers close to the body, and thereby the formation of four regions of vorticity each cycle.
Journal ArticleDOI
Vortex shedding from oscillating bluff bodies
TL;DR: In this paper, the authors present a comprehensive review of vortex shedding in two-dimensional bluff-body wakes and present irrespective of whether the separating boundary layers are laminar or turbulent, and if the body is flexible this can cause oscillations.
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).
