Analytical and experimental results: creation of a duffing acoustic nonlinear oscillator at low amplitudes
Maxime Morell, Manuel Collet, Emmanuel Gourdon +2
Nonlinear dynamics have long been exploited in order to damp vibrations in solid mechanics. The phenomenon of irreversible energy transfer from a linear primary system to a nonline…
Smart Acoustic Lining for UHBR Technologies Engine Part 2: acoustic treatment at the intake of a scaled turbofan nacelle
E. De Bono, M. Collet, K. Billon +5
The new generation of Ultra-High-By-Pass-Ratio (UHBR) turbofan engine while considerably reducing fuel consumption, threatens higher noise levels at low frequencies because of its…
Smart Acoustic Lining for UHBR Technologies Engine Part 1: design of an electroacoustic liner and experimental characterization under flow in rectangular cross-section ducts
E. De Bono, M. Collet, K. Billon +5
The new generation of Ultra-High-By-Pass-Ratio (UHBR) turbofan engine while considerably reducing fuel consumption, threatens higher noise levels at low frequencies because of its…
Design and experimental validation of a finite-size labyrinthine metamaterial for vibro-acoustics: enabling upscaling towards large-scale structures
Svenja Hermann, Kévin Billon, Alina-Michelle Parlak +3
In this paper, we present the design and experimental validation of a labyrinthine metamaterial for vibro-acoustic applications. Based on a 2D unit cell, different designs of finit…
The Advection Boundary Law in absence of mean flow: passivity, nonreciprocity and enhanced noise transmission attenuation
Emanuele De Bono, Manuel Collet, Morvan Ouisse
Sound attenuation along a waveguide is intensively studied for applications ranging from heating and air-conditioning ventilation systems, to aircraft turbofan engines. In particul…
