Abstract

The overall objective of the STENO project was the reduction of the turbulent trailing-edge noise, which is the dominant aeroacoustic noise source for state-of-the-art blades, using serrated trailing edges. A second objective was the adaptation and verification of a prediction algorithm for trailing-edge noise with which the aeroacoustic behaviour of wind turbine blades could be guessed a priori.
Serrations were designed and tested in free-field experiments considering different sizes and orientations of the serrations.
