Vortex-induced vibration - Wikipedia
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. …
Self-excited oscillations - this type of VIV is what occurs naturally, i.e., when the vortex-shedding frequency and the natural frequency are approximately the same. (This is the real VIV – this is …
VORTEX-INDUCED VIBRATIONS - Annual Reviews
This review summarizes fundamental results and discoveries concerning vortex-induced vibration (VIV), that have been made over the last two decades, many of which are related to the push …
Vortex Induced Vibration - an overview | ScienceDirect Topics
Vortex-induced vibrations (VIV) refer to the oscillations that occur on bluff bodies or structures when subjected to periodic vortex shedding resulting from the separation of boundary layers in …
[PDF] Vortex-Induced Vibrations - Semantic Scholar
Vortex-induced vibration (VIV) is the turbulent motion induced on bluff body that generates alternating lift forces and results in irregular movement of the body. VIV-powered system …
Vortex Shedding and Vortex Induced Vibrations Consider a steady °ow Uo on a blufi body with diameter D. Fy Fx Uo D We would expect the average forces to be: Fy Fx t F The measured …
Vortex-Induced Vibration (VIV) - University of Waterloo
As a classic fluid-structure interaction (FSI) phenomenon, vortex-induced vibration (VIV) refers to the motion on the structure induced by the periodic irregularities on the interacting external flow.
Vortex-induced vibration of solid structures has been known since ancient times, and remains a very important problem of fluid mechanics. Experimental studies of the vortex-induced …
We present new vortex wake modes, generally in the framework of a map of vortex modes compiled from forced vibration studies, some of which cause free vibration.
Vortex-Induced Vibrations - SpringerLink
Vortex-induced vibrations can be a serious concern for operations and for the structural integrity of mooring cables, towing hawsers, marine risers, and moored bluff structures, such as spar …
