The propagation of pressure disturbances is investigated in an annular duct with mean potential axial and swirling flow. The swirling mean motion causes refraction of the acoustic waves as they propagate along the duct. A normal mode analysis leads to a non-linear eigenvalue problem. The numerical s

Lined ducts often form a part of practical flow duct acoustic systems. The prediction of attenuation in such a duct has been a topic of research for many years. As far as the authors' knowiedge goes, the analysis of lined ducts with sheared mean flow has always been done numerically. In this paper,
