METHOD FOR REDUCING NOISE, VIBRATIONS, AND PRESSURE PULSATIONS ASSOCIATED WITH AERODYNAMIC INTERACTIONS BETWEEN WIND TURBINE BLADE WAKES AND THE WIND TURBINE TOWER
METHOD FOR REDUCING NOISE, VIBRATIONS, AND PRESSURE PULSATIONS ASSOCIATED WITH AERODYNAMIC INTERACTIONS BETWEEN WIND TURBINE BLADE WAKES AND THE WIND TURBINE TOWER
A noise, vibration, and pressure pulsation reducing collar for a wind turbine having a stationary tower, nacelle and rotor, a method of using such a reducing collar, and a wind turbine system comprising a said reducing collar are disclosed. The wind turbine includes rotating rotor blades, a nacelle containing an electric generator, and a stationary vertical supporting tower. The tower is provided with a reducing collar mounted thereon. The reducing collar can include elements of, e.g., rods or tubes or perforations or corrugations extending parallel to and along or adjacent to the outer surface of the tower and located downstream of the rotor blades.
