WebAbstract Trailing edge (TE) serrations are widely used as an effective passive control method to reduce the turbulent TE noise from wind turbine blades. Other than the acoustic effects, the aerodynamic performance of serrations is also an important issue that should be considered, since it determines the power output of the blade. WebAnswer (1 of 2): From study of the remarkably quiet performance of owls in flight, it is generally established that reductions of current wind turbine noise can be achieved by seriation of trailing edges of current wind turbine blade designs. Recent tests have shown some noise reduction may be po...
