Vortex shedding suppression and wake control: A review
TL;DR: In this article, a survey of existing studies on different methods of controlling the wake destructive behavior and suppression of vortex shedding behind bluff bodies are discussed, including the very recent developments, and the effectiveness of each technique on the drag reduction.
Journal ArticleDOI
Flow around a circular cylinder with slit
TL;DR: In this paper, a cylindrical test model is modified with a slit parallel to the incoming airflow to create a flow communicating channel between the windward and leeward stagnation points.
Journal ArticleDOI
Pressure distribution, fluctuating forces and vortex shedding behavior of circular cylinder with rotatable splitter plates
TL;DR: In this paper, a wind tunnel experiment on the flow around a circular cylinder with diameter D (40mm) attached with ten splitter plates freely rotatable around the cylinder axis has been carried out with different ratios of length to cylinder diameter (L / D ) from 0.5 to 6.0, in a range of Reynolds number from 3×10 4 to 6×104.

A mini review of recent progress on vortex-induced vibrations of marine risers
TL;DR: In this article, a review of the latest progress on the vortex-induced vibration (VIV) in marine risers is presented, including the multi-mode response, VIV response at high Reynolds numbers, flow-induced vibrations between multiple marine RISers, VIG of inclined risers and intermittent VIV in oscillatory flow.

The passive control of wake flow behind a circular cylinder by parallel dual plates
TL;DR: In this paper, the wake control of a circular cylinder by dual plates symmetrically attached at the rear surface is numerically investigated within the laminar flow regime, and it is shown that the attachment angle has a crucial effect on the control efficiency.

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.

An overview of modeling and experiments of vortex-induced vibration of circular cylinders
Rene D. Gabbai,Haym Benaroya +1 more
TL;DR: A review of mathematical models used to investigate vortex-induced vibration (VIV) of circular cylinders is given in this article, with a focus on single-degree-of-freedom (SFOF) models.
Journal ArticleDOI
The effect of two degrees of freedom on vortex-induced vibration at low mass and damping
TL;DR: Although there are a great many papers dedicated to the problem of a cylinder vibrating transverse to a fluid flow, the authors observes a rather dramatic departure from previous results, which would suggest a possible modification to offshore design codes.
