The propagation of acoustic waves in a duct of nearly annular cross-section is investigated. A method, based on a perturbation technique, is developed for calculating the wavenumbers of the propagating modes. Numerical results are presented for the case of (1) an annular duct having an elliptical ou

An experimental and theoretical investigation of the in#uence of a parallel shear #ow on the sound propagation in a circular duct is described. The theoretical model is based on a perturbation expansion at low Mach number of the modal equation for parallel shear #ows (Pridmore-Brown equation). In th
