Conventional rigid porous materials such as wools or foams do not provide effective absorption at low frequencies in complex industrial environments. For these applications, the structures developed are generally quarter-wave resonators or Helmholtz resonators. In recent years, 3D printing techniques have made it possible to produce resonator geometries that were previously difficult to produce. The ease of use and affordability of these techniques means that it is now possible to create tailor-made absorbing devices to meet specific requirements very quickly. This long-term objective requires, on the one hand, validation of the reliability of the dimensions obtained during the production of absorbent structures and, on the other hand, the ability to effectively model a variety of geometries in different contexts. In this thesis, stereolithography was chosen to print the samples based on literature results. Studies have concluded that it is more accurate for acoustic devices than other techniques. The geometry chosen for this study consists in a stack of volumes (spherical or cubic), connected in the three directions of space by channels in the image of cubic crystals. A large number of samples were manufactured varying the production parameters in order to measure the variability of the characteristic dimensions of the samples. Among the various modelling approaches presented, the numerical tests carried out led to the choice of equivalent fluid modelling based on the identification of JCAPL parameters. They are identified in a representative volume homogenised throughout the sample. This homogenisation of behaviour is suited to the geometries studied because of their periodic nature. The reaction of the geometries we are considering makes impedance modelling impossible. The samples are first studied at normal incidence, in order to link the variability of realisation to the measured acoustic behaviour. The measurement results and the predictions are in good agreement. Some samples were made specifically for duct wall measurement, in order to validate the use of the equivalent fluid approach. These tests were also used to confirm the conclusions drawn for normal incidence. The variability of the geometry has a real impact on the acoustic behaviour, but the main problem with rigid 3D printed samples is their adaptation to the measurement benches

Acoustic liners are a key technology in aeronautics for the passive reduction of the noise generated by aircraft engines. They are employed in a complex flow scenario in which the acoustic waves, the turbulent flow, and the acoustic liner are interacting.During this thesis, in a context of high performance computing, a compressible Navier-Stokes solver has been developed to perform implicit large eddy simulations of a model problem of this interaction: a turbulent plane channel flow with one wall modeled as an impedance condition.As a preliminary step the wall-turbulence in rigid channel flows and associated large-scale motions are investigated. A straightforward algorithm to detect these flow features is developed and the effect of compressibility on the flow structures and their contribution to the drag are studied. Then, the interaction between the acoustic liner and turbulent flow is investigated assuming periodicity in the streamwise direction. It is shown that low resistance and low resonance frequency tend to trigger flow instability, which modifies the conventional wall-turbulence and also results in drag increase.Finally, the simulation of a spatial channel flow was addressed. In this case no periodicity is assumed and an acoustic wave can be injected at the inlet of the domain. The effect of turbulence on sound attenuation is studied without liner, before a liner is introduced on a part of the channel bottom wall. In this more realistic case, it is confirmed that low resistance acoustic liners trigger an instability at the leading edge of the liner, resulting in drag increase and excess noise generation
