Vortex-Induced Vibrations

2016
Starting at a low Reynolds number of about 50, and reaching the highest Reynolds numbers recorded, bluff bodies placed within an external flow form an unstable wake that results in the formation of a regular pattern of vortices, the Karman street. If the structure is flexible or flexibly mounted, these vortices may cause vibrations, leading to stresses

Vortex-induced vibrations of a sphere

Journal of Fluid Mechanics, 2005
There are many studies on the vortex-induced vibrations of a cylindrical body, but almost none concerned with such vibrations for a sphere, despite the fact that tethered bodies are a common configuration. In this paper, we study the dynamics of an elastically mounted or tethered sphere in a steady flow, employing displacement, force and vorticity ...

Lock-in in vortex-induced vibration

Journal of Fluid Mechanics, 2016
The phenomenon of lock-in in vortex-induced vibration of a circular cylinder is investigated in the laminar flow regime ($20\leqslant Re\leqslant 100$). Direct time integration (DTI) and linear stability analysis (LSA) of the governing equations are carried out via a stabilized finite element method.
