Chaotic vortex induced vibrations [PDF]
Physics of Fluids, 2014 This study investigates the nature of the dynamic response of an elastically mounted cylinder immersed in a free stream. A novel method is utilized, where the motion of the body during a free vibration experiment is accurately recorded, and then a second experiment is conducted where the cylinder is externally forced to follow this recorded trajectory.

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
