dc.description.abstract | This report deals with structural vibrations of wind exposed structures caused by the vortex
shedding phenomena. The theory of vortex shedding and the field of study called aeroelastisity
are presented.
A case study of a light mast structure has been used as a study of the vortex shedding
phenomena. Numerical simulations of vortex shedding have been performed through the
use of Computational Fluid Dynamics (CFD). The aerodynamic flow around an U-section
suiceptable to vortex-induced vibrations has been evaluated. Three different aerodynamic
supression devices for vortex-induced vibrations have been presented and discussed.
An attempt was also made to perform Fluid-Structure Interaction (FSI) analysis. But as
computational stability problems were encountered, these attempts were not successful. | no_NO |
