Two-degree-of-freedom flow-induced vibration of two circular cylinders with constraint for different arrangements
TL;DR: In this article, the effects of arrangement and constraint on flow-induced vibrations (FIV) characteristics, including trajectory, vibration response, force response, and near wake structure, were analyzed.
Journal ArticleDOI
Vortex-induced vibrations of two rigidly coupled circular cylinders in tandem arrangement
TL;DR: In this article , the transverse vortex-induced vibrations (VIV) of two rigidly connected circular cylinders of equal size, arranged in a tandem configuration, were investigated by means of two-dimensional numerical computations.
Journal ArticleDOI
Vortex-induced vibration of two rigidly coupled tandem square cylinders at a low Reynolds number
TL;DR: In this article , two rigidly coupled tandem square cylinders with center spacing L=4 B were numerically investigated at a Reynolds number of Re=150, and the results reveal that the onset of the synchronization region for rigidly coupling cylinders is earlier than that without connection.
Journal ArticleDOI
Effect of three tandem cylinder diameter difference on flow-induced vibrations and heat transfer
TL;DR: In this paper , the effect of diameter differences of three tandem cylinders on flow-induced vibrations (FIVs) and convection heat transfer characteristics was investigated, and the authors found that the FIV of the downstream cylinder is reduced with the increase in diameter reduction ratio.
Journal ArticleDOI
Vortex-induced vibrations of two tandem rigidly coupled circular cylinders with streamwise, transverse and rotational degrees of freedom
TL;DR: In this paper , the effects of rigid coupling and the vibration degrees of freedom on the vortex-induced vibrations (VIV) of two tandem circular cylinders for a spacing ratio L/D = 4 at a Reynolds number of 150.

Flow-Induced Vibration
R. D. Blevins,H. Saunders +1 more
TL;DR: In this paper, the authors focus on applications for offshore platforms and piping; wind-induced vibration of buildings, bridges, and towers; and acoustic and mechanical vibration of heat exchangers, power lines, and process ducting.
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).
Journal ArticleDOI
Coupling of Structure and Wake Oscillators in Vortex-Induced Vibrations
TL;DR: A class of low-order models for vortex-induced vibrations is analyzed in this article, where a van der Pol equation is used to describe the near wake dynamics describing the fluctuating nature of vortex shedding and several types of linear coupling terms modelling the fluid-structure interaction are considered.
