Serrated noise reducer for a wind turbine rotor blade

A rotor blade assembly for a wind turbine, the rotor blade assembly comprising:

• a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a blade tip and a blade root;
• and,
• at least one noise reducer secured at the trailing edge, the noise reducer comprising a plurality of serrations, each of the of serrations comprising opposing side edges, each of the serrations comprising a radius of curvature extending between the opposing side edges, wherein all of the radius of curvatures of the plurality of serrations are oriented in a uniform direction, the radius of curvatures being configured to reduce vortices generated by the side edges of the serration.
