Résumé :

Despite the enormous political and financial efforts in order to promote the development and implementation of alternative technologies for the energy production, modern societies are still strongly dependent on the exploitation of fossil fuels. This does not only pose questions about the security of the future energy supplies and their costs, but it also constitutes a serious threat to the environment and human health. Different problems arise from the use of nuclear plants for electricity production and the possible occurrence of catastrophic events such as the accident of Fukushima in 2011. All the strategies implemented in order to face such problematics, from the design of more efficient engines and turbines for reduced fuel consumption to the formulation of alternative and cleaner fuels or the employment of more efficient safety systems in nuclear buildings, are based on CFD simulations. The accuracy of these simulations, which is strictly associated to the efficiency of the mitigation strategies, is linked to our fundamental understanding of the chemistry involved in the thermal decomposition and oxidation of the real fuels. The research results concerning fuel components and mixtures presented in the HDR thesis defense will be arranged based on three main areas of interest: 1) safety of nuclear plants (hydrogen related risks and flame dynamics); 2) formation of pollutants for cleaner combustion devices (detailed species profiles and exploration of potential energy surfaces); 3) combustion properties of fuel mixtures for higher combustion efficiencies (ignition delay times and laminar flame speeds). These investigations involve various multi-disciplinary aspects related to the combustion field, from the development of experimental techniques to their application to complex kinetic studies, from the validation of chemical kinetic models to theoretical ab-initio calculations for modeling purposes. Research perspectives will also be given in particular in relation to the development of future combustion devices, energy resources, and material technologies starting from the fundamental understanding of the basic principles governing the energy release and the formation of combustion intermediates.
