✦ Synopsis

A method is presented which leads to very simple transcendental equations for the determination of wavenumbers or frequencies at which acoustic resonances occur in flow ducts of various geometries and with various boundary conditions. The method, which is based on complex residue theory, is approximate but nevertheless very accurate for most parameter values. Formulae and results are presented for a wide variety of configurations.

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
