The differential equations governing the transmission of one-dimensional sound waves in a non-uniform duct carrying a subsonic compressible mean flow have been the subject of a recent debate [1,2]. Of the two formulations presented, one is considered to be non-acoustical and the other as neglecting

The boundary condition at an impedance wall in a duct with a steady mean #ow requiring the speci"cation of the normal component of acoustic particle velocity is examined. It is found that when implemented in the weak formulation of the "nite element method it can be considerably simpli"ed. The bound
A numerical approach which involves discretization of the duct into a series of large number of short ducts called segments has been in vogue for analyzing wave propagation in non-uniform ducts of general shapes. In this paper, an improved segmentation approach for analyzing one-dimensional wave pro
