Beschreibung
Zusammenfassung:	A wind turbine tower structure with passive flow control means for suppressing vortex induced vibrations in said tower structure is described. The said passive flow control means comprises vortex generator units which each comprises a fin and a base through which the fin is attached to the surface of the tower structure. The vortex generator will influence the boundary layer around the tower structure and thereby suppressing vortex induced vibrations. Each of said fins comprises a rectangular plate being ar- ranged substantially radially in relation to the tower structure and in a plane being sub-stantially perpendicular to a longitudinal axis through the tower structure.
