Tunnelling effects for acoustic waves in slowly varying axisymmetric flow ducts
(ElsevierJournal of Sound and Vibration, 2016-06-22)
The multiple-scales Wentzel–Kramers–Brillouin (WKB) approximation is used to model the propagation of acoustic waves in an axisymmetric duct with a constriction in the presence of mean flow. An analysis of the reflection ...
Spectral study of the Laplace-Beltrami operator arising in the problem of acoustic wave scattering by a quarter-plane
(Oxford University PressQuarterly Journal of Mechanics and Applied Mathematics, 2016)
The Laplace-Beltrami operator on a sphere with a cut arises when considering
the problem of wave scattering by a quarter-plane. Recent methods developed
for sound-soft (Dirichlet) and sound-hard (Neumann) quarter-planes ...
The acoustic Green's function for swirling flow with variable entropy in a lined duct
This paper extends previous work by the authors (Journal of Sound and Vibration, 395:294-316,2017) on the acoustic field inside an annular duct with acoustic lining carrying mean axial and swirling flow so as to allow for ...
Stability analysis for n -periodic arrays of fluid systems
(Physical Review Fluids, 2017-11-01)
© 2017 American Physical Society. A computational framework is proposed for the linear modal and nonmodal analysis of fluid systems consisting of a periodic array of n identical units. A formulation in either time or ...
