Jean Boulvert,Jean Boulvert,Josué Costa-Baptista,Théo Cavalieri,Vicente Romero-García,Gwenael Gabard,E. R. Fotsing,Annie Ross,Maxime Perna,Jacky Mardjono,Jean-Philippe Groby +10 more
TL;DR: In this paper, a folded metaporous surface optimized to achieve sub-wavelength and broadband perfect absorption is presented, which consists of four different helicoidal cavities filled by porous media, which are structured and quasi-isotropic micro-lattices with a variable lattice constant.
Proceedings ArticleDOI
A Computational Mode Matching Approach for Propagation in Three-Dimensional Ducts with Flow
Proceedings ArticleDOI
Influence of mean flow gradients on fan exhaust noise predictions
TL;DR: In this article, the effect of the mean flow gradients on fan exhaust noise propagation is carried out using both analytical models for simplified problems and numerical methods for realistic configurations, and an assessment of the effects of these mean flow gradient terms on the refraction effect was carried out.
Journal ArticleDOI
Anisotropic adaptivity of the p-FEM for time-harmonic acoustic wave propagation
Hadrien Bériot,Gwenael Gabard +1 more
TL;DR: The paper presents several examples of the efficiency and robustness of the method for the propagation of acoustic waves on distorted meshes and/or in the presence of strong background mean flows.
Journal ArticleDOI
Boundary layer effects on liners for aircraft engines
TL;DR: In this paper, the acoustic modes of a circular duct with flow are calculated using a finite difference method, and a modified impedance condition including the effect of a small but finite boundary layer thickness is considered and compared to the standard Myers condition based on an infinitely thin boundary layer.
