Vortex-induced vibrations of a cylinder with tripping wires [PDF]
Journal of Fluid Mechanics, 2001 Thin wires are attached on the outer surface and parallel to the axis of a smooth circular cylinder in a steady cross-stream, modelling the effect of protrusions and attachments. The impact of the wires on wake properties, and vortex-induced loads and vibration are studied at Reynolds numbers up to 4.6 × 104, with 3.0 × 104 as a focus point. For a

Vortex-induced vibration of a rotating sphere [PDF]
Journal of Fluid Mechanics, 2017 Vortex-induced vibration (VIV) of a sphere represents one of the most generic fundamental fluid–structure interaction problems. Since vortex-induced vibration can lead to structural failure, numerous studies have focused on understanding the underlying principles of VIV and its suppression.

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