Unsteady lift forces generated by vortex shedding about a large, stationary, and oscillating cylinder at high Reynolds numbers.
TLDR
In this paper, a wind tunnel study of unsteady lift forces generated by vortex shedding about large, stationary, and oscillating cylinder at high Reynolds numbers is presented, showing that the lift forces are generated by a large and stationary, stationary and oscillated cylinder.Abstract:

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
A review of vortex shedding research and its application
TL;DR: A review of cylinders in steady currents can be found in this paper, where the effects of length/diameter ratio, cylinder surface roughness and channel blockage are discussed, and the results of tests with pane and three-dimensional frames are described and quantified in terms of isolated cylinder data.

Numerical simulation of flow around a smooth circular cylinder at very high Reynolds numbers
TL;DR: In this article, a 2D Unsteady Reynolds-Averaged Navier-Stokes (URANS) model with a standard high Reynolds number k- epsilon turbulence model is evaluated for engineering design in supercritical and upper-transition flow regimes.

Across-wind vibrations of structure of circular cross-section. Part II. Development of a mathematical model for full-scale application
R.I. Basu,B.J. Vickery +1 more
TL;DR: In this paper, a model is presented for predicting the across-wind response of slender structures of circular cross-section to turbulent shear flow, and a computer program is developed to obtain estimates of response in full-scale situations.

Unsteady forces on a circular cylinder at critical Reynolds numbers
TL;DR: In this paper, large-eddy simulations of the flow past a cylinder at Reynolds numbers in the range 2.5 × 105-6.5× 105 are performed, and it is shown how the pressure distribution changes as the Reynolds number increases in an asymmetric manner, occurring first on one side of the cylinder and then on the other side to complete the drop in the drag up to 0.23.

The Lift and Drag Forces on a Circular Cylinder Oscillating in a Flowing Fluid
TL;DR: In this article, a circular cylinder was placed in a flowing fluid with its axis across the stream and the fluctuating lift and drag forces, and the steady drag force were measured.
Low-speed drag of cylinders of various shapes
Noel K Delany,Norman E Sorensen +1 more
TL;DR: In this paper, the approximate variation of the drag coefficient with Reynolds number of several cylinders with different cross-sectional shapes was investigated, and data were obtained for circular cylinders, elliptical cylinders, rectangular and diamond cylinders of three fineness ratios, and two isosceles triangular cylinders.

Fluctuating Lift and Drag Acting on a Cylinder in a Flow at Supercritical Reynolds Numbers
TL;DR: In this article, the root-mean-square values of the lift and drag coefficients, the extreme values of these coefficients, and their power spectra at various Reynolds numbers are presented.
Experimental investigation of wind induced oscillation effects on cylinders in two-dimensional flow at high Reynolds numbers
TL;DR: Steady drag and unsteady lift forces on circular cylinder subjected to two-dimensional wind flow were reported in this article, where the cylinder was subjected to a two dimensional wind flow and a circular cylinder was used.
