The non-linear equations appropriate to the transmission of sound in a duct are derived from the equations of fluid dynamics. A numerical method is described by which solutions are obtained. For low sound pressure levels the numerical solution is shown to provide results in close accord with theory

The propagation of sound in elliptic ducts has been investigated as a model case to indicate the acoustic effects of departures from symmetry in a circular duct. The cut-off frequencies of the higher order circumferential modes in an elliptic duct have been calculated for various duct eccentricities

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
