Abstract
The present disclosure relates to devices () for wind turbine blades () and methods () for reducing vibrations in wind turbines (). More particularly, the present disclosure relates to devices () for mitigating vortex induced vibrations and stall induced vibrations, wind turbine blades () comprising such devices (), and methods () for reducing wind turbine vibrations when the wind turbine () is parked, especially during wind turbine installation and/or maintenance. A device () is configured to be arranged around a wind turbine blade () and comprises three or more air flow modifying elements () comprising a concave outer surface () configured to face away from a wind turbine blade (). The device further comprises a supporting structure () configured to support the plurality of air flow modifying elements (). An angular distance () between adjacent air flow modifying elements () in cross-section is substantially constant.
