Numerical Investigation of Vortex-Induced Vibrations of a Rotating Cylinder near a Plane Wall

open access: yesJournal of Marine Science and Engineering, 2023
Numerical simulations are carried out to investigate the vortex-induced vibrations of a two-degree-of-freedom (2DOF) near-wall rotating cylinder. Considering the effects of gap ratio, reduced velocity and rotational rate, the amplitude response, wake ...

Numerical simulation of the airflow–rivulet interaction associated with the rain-wind induced vibration phenomenon [PDF]

open access: yes, 2011
Rain-wind induced vibration is an aeroelastic phenomenon that occurs on the inclined cables of cable-stayed bridges. The vibrations are believed to be caused by a complicated nonlinear interaction between rivulets of rain water that run down the cables ...

Study on the Effect and Mechanism of Aerodynamic Measures for the Vortex-Induced Vibration of Separate Pairs of Box Girders in Cable-Stayed Bridges

open access: yesShock and Vibration, 2015
Although not always resulting in catastrophic failures, vortex-induced vibration (VIV) response can seriously impact the fatigue life and functionality of bridges, especially for separate pairs of box girders in cable-stayed bridges.

Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators [PDF]

open access: yes, 2012
Many studies have typically applied a linear structural spring–mass–damper oscillator and a van der Pol wake oscillator to model a one-dimensional cross-flow vortex-induced vibration (VIV).

The galloping of a 4:1 rectangular cylinder at Re = 300

open access: yesAIP Advances, 2023
The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.

Visualization and Parametric Study on Vortex Shedding Suppression of Cylindrical Structures in Offshore Engineering Using Large Eddy Simulation

open access: yesJournal of Marine Science and Engineering, 2023
Cylindrical structures are widely used in offshore and marine engineering, but they may suffer from vortex-induced vibration under the influence of ocean or wave currents, which can lead to severe fatigue damage. In this study, we applied the open-source
