Numerical simulation of a forced and freely-vibrating cylinder at supercritical Reynolds numbers

Recent innovations in the off-shore wind industry have lead to bigger wind turbines and taller support structures. These towers can suffer from vortex-induced vibrations (VIV). The present work couples the open-source CFD solver OpenFOAM with a structural solver to investigate these fluid-structure interactions (FSI) effects in more detail. 2D...

Vortex-induced vibrations of a freely vibrating cylinder near a plane boundary:: Experimental investigation and theoretical modelling

This work reports on experiments that were performed with a freely vibrating cylinder exposed to currents and placed near a plane boundary parallel to the cylinder axis. It is observed that the proximity of the boundary affects the vertical response of the cylinder in two ways: (i) for gaps between 0.75 and 2 diameters (D), the amplitude of...
