Abstract

In this talk we present recent developments in the Rapid-distortion theory of turbulence when applied to the prediction of sound radiated by non-homogeneous turbulence interacting with a trailing edge of a semi-infinite flat plate positioned parallel to the level curves of an otherwise arbitrary mean flow field. The latter problem has received much attention in Aero-acoustics research community and is a canonical representation of jet installation effects.
