Abstract: A wind turbine includes a tower and a vortex-induced vibration (VIV) mitigation system configured on the tower. The VIV mitigation system has a rod attached to an outer surface of the tower and extending longitudinally along an axis of the tower. A plurality of strake support guides extend transversely from and are spaced apart along the rod, the strake support guides comprising a length and a shape to retain a strake supported thereon. A strake is wrapped in a helical pattern around the tower, wherein at least a plurality of wraps of the strake are laid on and supported by the strake support guides.

Abstract: A method for mitigating noise during high wind speed conditions of a wind turbine includes providing a backward twist to the outboard region of the rotor blade having an angle of less than 6°. The method may also include reducing a tip chord taper within at least a portion of the outboard region of the rotor blade. Further, the method may include increasing a local tip chord length of the rotor blade. In addition, the method may include increasing a torsional stiffness of the outboard region of the rotor blade. As such, a combination of one or more of the blade properties described above are configured to reduce noise associated with high wind speed conditions.

Abstract: The present disclosure is directed to a blade sleeve for a blade tip of a rotor blade of a wind turbine. The blade sleeve includes a rapid-prototyped body having a pressure side, a suction side, a first open span-wise end, a closed leading edge, and a trailing edge. Further, the body is slidable onto the blade tip of the rotor blade. In addition, the blade sleeve includes at least one additional rapid-prototyped feature integral with the body.

Abstract: An apparatus for mitigating vortex-shedding vibrations or stall-induced vibrations on one or more rotor blades of a wind turbine during standstill includes at least one positioning element located between a blade tip section and a blade root section thereof. The positioning element is adapted for wrapping around at least a portion of the rotor blade. The apparatus also includes at least one airflow modifying element coupled to the positioning element and defining a height relative to a surface of the rotor blade. Additionally, the apparatus includes at least one securing element operably coupled to the positioning element for temporarily securing the airflow modifying element to the rotor blade.

Abstract: A method for providing visual identification of a flow field across one or more wind turbines includes releasing at least one tracer material from at least one predetermined location of the wind turbine. The method also includes synchronizing the releasing of the tracer material with at least one of one or more operating parameters or one or more wind parameters of the wind turbine. Further, the method includes monitoring, via one or more sensors, a resultant flow pattern of the tracer material from one or more uptower locations.
