Finite amplitude acoustic waves (FAAWs) that propagate in a two-dimensional rectangular duct of semi-infinite length as a result of periodic excitation are determined by using second-order perturbation, based on the partial wave analysis method. With second-harmonic boundary and initial conditions o

The recent interest in propeller noise generation, stimulated by development of new propeller types for commercial propjets, has generated a need for the ability to measure the noise characteristics of propellers. However, wind tunnel noise measurements are affected by reflections from the wind tunn
## Communicated by W. SprΓΆΓig The diffraction of acoustic waves by an infinitely long annular duct having a finite gap on the inner wall is investigated rigorously. The related boundary-value problem is formulated into a modified Wiener-Hopf equation, which is then reduced to a pair of simultaneou
