The aeroacoustic phenomena of flap side edge noise and the associated noise source mechanisms are discussed. Further, a systematic and parametric wind tunnel study is presented which considers generic side edge models instead of specific flap side ed

Main objective of the present work is the development of a three-dimensional model of Special Acoustic Absorbers (SAAs) and its application to SAA acoustic performance prediction. These absorbers consist of a circular volume with an inserted horn of
