New insights into mode behaviours in waveguides with impedance boundary conditions
Wenping Bi, Vincent Pagneux
In this paper we investigate mode nonorthogonal properties and their effects on the sound power attenuation in a waveguide with impedance boundary conditions. By introducing two qu…
Asymmetric acoustic propagation of wave packets via the self-demodulation effect
Thibaut Devaux, Vincent Tournat, Olivier Richoux +1
This article presents the experimental characterization of nonreciprocal elastic wave transmission in a single-mode elastic waveguide. This asymmetric system is obtained by couplin…
Multiple scattering of elastic waves by pinned dislocation segments in a continuum
Dmitry Churochkin, Felipe Barra, Fernando Lund +2
The coherent propagation of elastic waves in a solid filled with a random distribution of pinned dislocation segments is studied to all orders in perturbation theory. It is shown t…
Slow Sound in a duct, effective transonic flows and analogue black holes
Yves Aurégan, Pierre Fromholz, Florent Michel +2
We propose a new system suitable for studying analogue gravity effects, consisting of a gas flowing in a duct with a compliant wall. Effective transonic flows are obtained from uni…
Slow sound in lined flow ducts
Yves Auregan, Vincent Pagneux
We consider the acoustic propagation in lined flow duct with a purely reactive impedance at the wall. This reacting liner has the capability to reduce the speed of sound, and thus…
