Texto completo da fonteMultiple scattering and non linear effects are antagonists so it is not commun to observea coupling of those two effects. In acoustics, non linear effects are important when they are cumulative,therefore dispersion relation is modified by multiple scattering and non linear effects cannotbe cumulative. Bubbles are known to have a non linear behavior and also to be good scatterers witha scattering cross section higher than the geometric cross section at resonance frequency. Therefore,bubbly media seem to be good to observe multiple scattering in non linear regime. A bubbly-mediumhas three different regimes. At low frequency, non linear effects are important and cumulative butthere is no multiple scattering effects. At bubbles resonance frequency, non linear behavior and alsomultiple scattering effects are important but the non linear effects cannot be cumulative. At high frequency,multiple scattering effects are important but without no non linear effects. The experimentsin this thesis show, on the one hand, a high frequency wave propagating in a bubbly-medium andon the other hand, the resonance frequency wave propagation. At high frequency, a coda is observedin experiment and modeled by a diffusion equation. At resonance frequency, the model, confirmed bythe experiments, leads us to some applications : acoustic frequency doubler, acoustic diode and phaseconjugation mirror

Texto completo da fonteIn this thesis, opération of the parametrie antenne in unconsolidated granuler mate- rials is studied. The parametrie antenne, widely used in underwater acoustics, involves a nonlinear acoustie effect that can be interpreted as an amplitude self-demodulation Several models of parametrie antenna are developed to take into account absorption, scattering, or dispersion phenomena, as well as évanescent feature of the waves. Experiments in disordered packings of glass beads, in qualitative agreement with theoretical prédictions are performed. Shear waves for emission are used for the first time, and produce a low frequency demodulated longitudinal signal. This nonlinear dilatancy phenonienon is tested in different expérimental configurations and is shown to be very sensitive to the nonlinear anisotropy of the force chains network

Texto completo da fonteThis PhD thesis is devoted to the study of two reaction-diffusion models arising in Inertial Confinement Fusion. In chapter 1 we derive a new thermodiffusive model, describing a stabilization at short wave-lengths by transversal mass ablation. A self-consistent analysis [SMC06] of the full thermo-hydrodynamical model yielded a heuristic dispersion relation. It was suggested in [Masse,Clavin 2004] that the stabilization can be investigated looking at a much simpler model, namely the linear relaxation of wrinkled fronts. A first rigorous analysis was performed for an approximated model in [Clavin,Masse,Roquejoffre 2011], where a very similar dispersion relation was obtained. We prove here that, in the context of a longitudinal flow approximation, the dispersion relation obtained in our model is exactly the self-consistent one. In chapter 2, we establish an existence result for traveling wave solutions in some non-linear flame model with a shear flow and growth condition at infinity in the propagation direction. We show that this solutions exists for propagation speeds larger than some critical speed explicitly computed in terms of the flow. This solution, which has a free boundary, is very similar to the planar traveling wave existing for the Porous Media Equation. The main novelty is here the presence of a prescribed longitudinal shear flow. In the last chapter we use numerical simulations to investigate the free boundary, in which corners seem to appear. We give a semi-heuristic argument, which may allow one to study the free boundary regularity and its geometrical description
