<p>A wind turbine rotor blade is provided, having a root end, a tip end, a leading edge section, a trailing edge section and a serrated extension, wherein the serrated extension is attached to the trailing edge section and has at least a first tooth. Furthermore, the wind turbine rotor blade has at least one patterning element for guiding a wind flow which is flowing from the leading edge section to the trailing edge section such that noise which is generated at the trailing edge section is reduced. The patterning element has the shape of a ridge. Advantageously, the ridge-shaped patterning element is located upstream, compared to the first tooth, and/or is located on a surface of the first tooth. Furthermore, a method is provided to reduce noise which is generated at a trailing edge section of a wind turbine rotor blade.</p> |
