Combined interface boundary condition method for fluid–rigid body interaction
TL;DR: Jiao et al. as mentioned in this paper presented a new loosely-coupled partitioned algorithm for fluid-structure interaction (FSI) which is intrinsically exposed to the notorious time lag effect whose remedy promotes the combined interface boundary condition (CIBC) method.

Vibrations of a square cylinder submerged in a wake
Rajesh Bhatt,Md. Mahbub Alam +1 more
TL;DR: In this paper, a numerical investigation is conducted on the flow around and vibration response of an elastic square cylinder (side width) and different facets are discussed in terms of wake structures, work done and phase lag between lift and displacement.

Flow-induced vibration of a circular cylinder with rigid splitter plate
TL;DR: In this paper, the effect of the length of the splitter plate on the amplitude and amplitude of the FIV was studied for a single cylinder with an attached rigid splitter.
Journal ArticleDOI
Mode competition in galloping of a square cylinder at low Reynolds number
TL;DR: In this article, the authors reveal the underlying mechanisms of galloping of a square cylinder at low Reynolds numbers via linear stability analysis (LSA) and direct numerical simulations, and conclude that transverse galloping is essentially a kind of single-degree-of-freedom (SDOF) flutter, superimposed by a forced vibration induced by the natural vortex shedding.

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.

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
A critical review of the intrinsic nature of vortex-induced vibrations
TL;DR: A comprehensive review of the progress made during the past two decades on vortex-induced vibration (VIV) of mostly circular cylindrical structures subjected to steady uniform flow is presented in this article.
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.
