Full textA detailed theoretical and numerical investigation of the behaviour of reactive systems under the influence of chaotic stirring is presented. These systems exhibit stationary solutions arising from the balance between chaotic advection and diffusion. Excessive stirring of such systems results in the termination of the reaction via a saddle-node bifurcation. The solution behaviour of these systems is analytically described using a recently developed nonperturbative, non-asymptotic variational method. This method involves fitting appropriate parameterised test functions to the solution, and also allows us to describe the bifurcations of these systems. This method is tested against numerical results obtained using a reduced one-dimensional reaction-advection-diffusion model. Four one- and two-component reactive systems with multiple homogeneous steady-states are analysed, namely autocatalytic, bistable, excitable and combustion systems. In addition to the generic stirring-induced saddle-node bifurcation, a rich and complex bifurcation scenario is observed in the excitable system. This includes a previously unreported region of bistability characterised by a hysteresis loop, a supercritical Hopf bifurcation and a saddle-node bifurcation arising from propagation failure. Results obtained with the nonperturbative method provide a good description of the bifurcations and solution behaviour in the various regimes of these chaotically stirred reaction-diffusion systems.

Full textThis work deals with the optimization of the geometry of a reverberation chamber, drawing inspiration from the concept of chaotic cavity. Reverberation chambers, widely used for electromagnetic compatibility tests, are used above a minimal frequency from which the fields are statistically isotropic and uniform; however to respect these properties, a mode stirring process is necessary, that can be mechanical or electronic. As, in chaotic cavities, most modes are isotropic and uniform without the help of any stirring process, we take advantage of the knowledge gained from the studies of chaotic cavities to optimize reverberation chamber behavior.We firstly consider 2D chaotic cavities obtained by modifying a rectangular cavity. Measurements besed on a perturbative approch, and validated by simulations, show uniformly distributed electric fields. Similar geometrical modifications are then proposed in 3D.Three 3D different geometries of cavities obtained from a 3D rectangular cavity are then studied, and their properties are compared with those of a classical reverberation chamber equipped witdh a mode stirrer. Eigenmodes and resonant frequencies are determined numerically using Ansoft HFSS software, first by considering fixed cavity geometries, then by moving the stirrer.Electric field uniformity and isotropy are studied using several criteria; all of them clearly show that the best performances are attained within one of the proposed chaotic cavities.Moreover, a strong energy localization effect appears for numerous modes in the classical reverberation chamber, whereas it is not observed in the proposed 3D chaotic cavity. This effect, never reported in reverberation chamber studies, affects the field uniformity and isotropy within the working volume.The cavities properties are also compared width respect to their eigenfrequency spacing distributions. As predicted by the Random matrix Theory, the best agrement width the asymptotic law associated to chaotic cavities corresponds to the best field properties in terms of uniformity and isotropy. It leads to the proposal of reverberation chamber characterization criteria based on resonant frequencies instead of field distributions
