Investigation of the noise reduction potential of trailing-edge serrations at low-to-moderate Reynolds number. Flow and noise data were measured for a flat plate with serrations in an anechoic wind tunnel. Velocity data are related to noise measurements to gain insight into the effect of serrations on the emitted noise.
