Nonlocal description of sound propagation through an array of Helmholtz resonators
Navid Nemati, Anshuman Kumar, Denis Lafarge +1
A generalized macroscopic nonlocal theory of sound propagation in rigid-framed porous media saturated with a viscothermal fluid has been recently proposed, which takes into account…
Transients in porous media: asymptotic time-domain Green functions and limits of current frequency-domain models
Jean Kergomard, Denis Lafarge, Joël Gilbert
Time domain responses of porous media have been studied by some authors, but generally the possible descriptions have been given in the frequency domain. The aim of this paper, lim…
Multiple Scattering and Visco-Thermal Effects on 2D Phononic Crystal
Aroune Duclos, Denis Lafarge, Vincent Pagneux
In this paper, we are interested in the transition between regimes here either visco-thermal or multiple scattering effects dominate for the propagation of acoustic waves through a…
