Modélisation et simulation multi-niveaux de la combustion d’une thermite composée de nanoparticules Al/CuO : des phénomènes microscopiques à la simulation du système en combustion

Abstract : This thesis work deals with understanding and modeling the combustion of a mixture of nanoparticle made of aluminum and metal oxide. In this context, we developed a kinetic model, based on multiple elementary phenomena : diffusion, reaction, condensation, vaporization and decomposition. We showed that this model allows to predict the evolution of the pressure generated during the combustion as a function of multiple parameters : packing, proportion of aluminum and metal oxide, and particle sizes. Finally, this model have been coupled with a description of the thermal transport, in order to study the effect of heat losses in a combustion chamber.
