Acoustic waves in ducts with sinusoidally perturbed walls and mean flow
(Acoustical Society of America, 1975)
An analysis is presented of the propagation of acoustic waves in a hard-walled duct with sinusoidally perturbed walls and carrying mean flow. The results show that resonance occurs whenever the wavenumber of the wall ...
Sound waves in two-dimensional ducts with sinusoidal walls
(Acoustical Society of America, 1974)
The method of multiple scales is used to analyze the wave propagation in two-dimensional hard-walled ducts with sinusoidal walls. For traveling waves,resonance occurs whenever the wall wavenumber is equal to the difference ...
