Excitation, inertia, and drag forces on a cylinder vibrating transversely to a steady flow
TLDR
In this paper, the authors present a computational study of the forces on a cylinder oscillating harmonically in the direction perpendicular to a uniform flow, where the two-dimensional Navier-Stokes equations are solved on a coordinate system fixed on the cylinder.About:

An investigation into the hydrodynamics of a flexible riser undergoing vortex-induced vibration
TL;DR: In this article, the hydrodynamic forces of a flexible riser undergoing vortex-induced vibration (VIV) based on measured strain is proposed, and an inverse method is adopted for the calculation of hydrodynamic forces in the cross flow (CF) and inline (IL) directions.

Wake dynamics of external flow past a curved circular cylinder with the free stream aligned with the plane of curvature
TL;DR: In this paper, the fundamental mechanism of vortex shedding past a curved cylinder has been investigated at a Reynolds number of 100 using three-dimensional spectral/hp computations, and two different configurations are presented.
Journal ArticleDOI
Numerical simulation of flow around an orbiting cylinder at different ellipticity values
TL;DR: In this paper, the Navier-Stokes equations, pressure Poisson equations and continuity are solved in primitive variables in a noninertial system fixed to the orbiting cylinder and solved by the finite difference method.

Chaos in a cylinder wake due to forcing at the Strouhal frequency
TL;DR: In this article, it was shown that a cylinder oscillating harmonically in line with an incoming flow at a frequency equal to the natural frequency of vortex shedding induces a chaotic state in the flow, characterized by an aperiodic lift force.

A time domain prediction method for the vortex-induced vibrations of a flexible riser
TL;DR: In this article, a time domain prediction method from experimental data is proposed for vortex-induced vibration (VIV) of flexible risers, where the nonlinear factors, couplings among axial tension, VIV response in cross flow (CF) direction and the hydrodynamic force, have been taken into account in this method, with a simplified tension variation model and empirical hydrodynamynamic force model.

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.
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.
Journal ArticleDOI
High-order splitting methods for the incompressible Navier-Stokes equations
TL;DR: Improved pressure boundary conditions of high order in time are introduced that minimize the effect of erroneous numerical boundary layers induced by splitting methods, and a new family of stiffly stable schemes is employed in mixed explicit/implicit time-intgration rules.
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.
