Serrations at the front end of wind turbine blades

Trailing edge serrations (TES) reduce the noise of the so called “turbulent boundary layer trailing edge noise”. A wind turbine blade is described having noise reduction features. The blade has a plurality of projecting serrations provided at the blade trailing edge to reduce the scattering noise produced during operation of the blade, wherein the serrations have a plurality of through-going apertures defined. Serrated edges on turbine blades break up airflow, creating smaller, less organized vortices that diffuse sound and quiet the blade. How Do Serrated Trailing Edges on Turbine Blades Work to Reduce Noise? Serrated trailing edges, also known as "combs" or "fringes," reduce noise by breaking up the. Serrations help to reduce noise emissions and bring the turbines back to a higher mode of operation. This can increase your AEP by up to 5%. This prototype is a horizontal-axis wind turbine, featuring three 76-meter blades and a 100-meter tower.
