A nonlinear numerical model shows that internal and external flows can couple the first and second bending modes of a cantilever pipe, producing lock-in and post-flutter responses that remain periodic ...

Vortex-induced vibrations (VIV) occur when fluid flows past a bluff body and alternately sheds vortices from its sides, generating periodic transverse forces that can excite structural oscillations.

Vortex induced vibration (VIV) is the vibration of an object caused by the flow of air or liquid around it. The vibration is caused by vortex shedding, a periodic instability that occurs in the wake ...

This study numerically investigates incompressible two-dimensional laminar flow around two rectangular cylinders arranged in tandem configuration using the lattice Boltzmann method (LBM). Simulations ...

Fluid flow across a flexible or elastically mounted structure causes vibrations due to vortex shedding and other similar instabilities, like galloping. The flow-induced vibrations (FIV) are ...

Vortex-Induced Vibration (VIV) suppression devices are installed on slender offshore structures—drilling and production risers, steel catenary risers (SCRs), top-tensioned risers (TTRs), umbilicals, ...

In the offshore subsea environment, weather disruptions and changes in the oceanic environment are common considerations for operators. Reducing the effects of such factors is key to keeping costs low ...
