The problem of transmission of sound in a narrow pipe carrying a mean flow has been dealt with in recent papers by solving the convected acoustic equations simplified in the manner of the Zwikker and Kosten theory. A significant difference between these studies appertains to the form of the axial me

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,
The sound pressure generated by a point mass monopole with arbitrary time dependence in a circular duct with uniform mean flow has been derived in the time domain. In a further step, the cross-correlation function and the cross-spectral density of the sound pressure between two microphone positions
