WebMarine risers (like any bluff body placed in a cross flow) create a vortex wake that induces cyclic loading. Unlike a complete platform, however, risers are...
In fluid dynamics, vortex-induced vibrations (VIV) are motions induced on bodies interacting with an external fluid flow, produced by, or the motion producing, periodic irregularities on this flow. A classic example is the VIV of an underwater cylinder. How this happens can be seen by putting a … Meer weergeven They occur in many engineering situations, such as bridges, stacks, transmission lines, aircraft control surfaces, offshore structures, thermowells, engines, heat exchangers, marine cables, towed … Meer weergeven • Aeroelastic flutter • Kármán vortex street • Vortex power Meer weergeven • Vortex induced vibration data repository • Design Principles for Ocean Vehicles Course, MIT Meer weergeven Much progress has been made during the past decade, both numerically and experimentally, toward the understanding of the kinematics (dynamics) of VIV, albeit in the low-Reynolds number regime.
