Journal ArticleDOI
Aerodynamics of nominally circular cylinders: A review of experimental results for Civil Engineering applications
TL;DR: In this article, a review of existing literature on experimental results of interest for Civil Engineering applications on the aerodynamics of cylinders whose geometry deviates from that of a perfect circular cylinder is presented.
Journal ArticleDOI
Cellular vortex shedding behind a tapered circular cylinder
TL;DR: In this paper, a tapered circular cylinder with taper ratio 75 placed normal to the inflow has been studied and it was observed that even with a very long time sampling a discrete cellular shedding pattern prevails.
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.
Journal ArticleDOI
Oblique vortex shedding behind tapered cylinders
TL;DR: In this paper, the full unsteady three-dimensional Navier-Stokes equations were solved numerically with the view of exploring the rather complex vortex shedding phenomena caused by the variation of the natural shedding frequency along the span of the cylinder.
Journal ArticleDOI
Stream-wise and cross-flow vortex induced vibrations of single tapered circular cylinders: An experimental study
TL;DR: In this paper, the results from in-water towing-tank experiments on the vortex-excited vibrations of tapered circular cylinders in a uniform flow are reported and discussed.

Journal ArticleDOI
Oblique and Parallel Modes of Vortex Shedding in the Wake of a Circular Cylinder at Low Reynolds Numbers
TL;DR: In this article, it was shown that the Strouhal discontinuity is not due to any of the previously proposed mechanisms, but instead is caused by a transition from one oblique shedding mode to another oblique mode.
Journal ArticleDOI
On the Wake and Drag of Bluff Bodies
TL;DR: In this article, a modification to Kirchhoff's free streamline introduces the parameter k = √(1-C_ps), which allows arbitrary base pressure and which must depend on the dynamics of the wake.

On vortex shedding from smooth and rough cylinders in the range of Reynolds numbers 6*10^3 to 5*10^6
E. Achenbach,E. Heinecke +1 more
TL;DR: In this article, the influence of surface roughness on the vortex shedding frequency in the wake of a single cylinder has been investigated in an atmospherical and a high-pressure wind tunnel.

Review : vortex shedding lock-on and flow control in bluff body wakes
Owen M. Griffin,Mary S. Hall +1 more
TL;DR: In this paper, it was shown that vortex shedding resonance or lock-on is observed also when a bluff body is placed in an incident mean flow with a periodic component superimposed upon it.
Journal ArticleDOI
Vortex splitting and its consequences in the vortex street wake of cylinders at low Reynolds number
TL;DR: In this article, it was shown that a design break line of vortex axes can lead to the decoupling of a wake flow from the always present disturbances deriving from the ends.
