A method of solution for the non-linear acoustic equations of an inviscid fluid in a duct with varying cross-section is given, which brings into evidence the following aspects of the problem: (i) the influence of the cross-section variation with respect to the wavelength; (ii) the influence of the n
The propagation of acoustic waves along a duct of elliptic cross-section, the eccentricity of which varies slowly along the axis, is considered as a model of the unsteady #ow inside a realistic aeroengine nacelle. This is a development of recent work on a circular duct by Rienstra. The acoustic "eld
