A rotor blade assembly for a wind turbine is disclosed. The rotor blade assembly includes a rotor blade having surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root. The rotor blade further includes a noise reducer configured on a surface of the rotor blade, the noise reducer comprising a plurality of serrations, each of the plurality of serrations defining a centerline. The centerline of each of the plurality of serrations defines a individual tailored angle dependent on at least one of...
