Ce livre porte sur la modélisation numérique d’un transformateur intégré. Le transformateur comprend deux bobines circulaires, primaire et secondaire, ayant les mêmes diamètres intérieur et extérieur, mais un nombre de spires différent. Les bobines sont déposées sur un substrat isolant en Kapton, lui-même placé entre deux substrats magnétiques en ferrite, séparés par un espace appelé gap. Le comportement physique est décrit par les équations de Maxwell pour l’électromagnétisme, couplées à l’équation de la chaleur pour le transfert thermique. Les hypothèses principales sont que la flottabilité de l’air vertical est négligeable et que les deux bobines agissent comme sources internes de chaleur. Le système d’équations aux dérivées partielles, avec conditions aux limites, est résolu par la méthode des éléments finis via le logiciel Comsol 6.0. L’étude détermine les paramètres géométriques du micro-transformateur et intègre l’effet Joule pour analyser le comportement thermique.

    This work is devoted to 1.5D numerical modeling of charged particle transport in filament-type out-of-equilibrium discharges. The chosen configuration is a planar tip in the gaseous medium nitrogen. We opted for a hydrodynamic model (drift-diffusion model) derived from the self-coherent coupling of the first two moments of the Boltzmann equation to the Poisson equation. The con...

  • Charged particle-wave interactions in space plasmas
    Aicha Flitti
    This book is dedicated to the study of charged particle interactions in space plasmas. These play a crucial role in many phenomena observed in space, such as auroras, solar winds, cosmic rays and many others. For the simulation, we used the PIC (Particle In Cell) method, considered to be the first method to have been developed historically for the simulation of the Vlasov Maxwe...
