On Thursday, December 13, 2018, Julien RAMOUSSE, PhD student in energy and process engineering at the Laboratoire Optimisation de la Conception et Ingénierie de l'Environnement (LOCIE), will present his thesis "Phenomenological modeling and thermodynamic analysis of energy conversion systems".
The defense will take place at 2pm, in room C104, Polytech Annecy-Chambéry building, on the Annecy campus.
Summary of the thesis
The current energy context calls for the implementation of innovative, high-efficiency solutions using hitherto under-utilized resources, with a view to a realistic and sustainable energy transition. In order to address these issues, the work presented focuses on the phenomenological modeling and thermodynamic analysis of various energy conversion systems, with a view to optimizing their performance. The systems addressed can be divided into two categories: - electrochemical systems (PEMFC fuel cells and microbial fuel cells), for direct conversion of chemical energy into electrical energy, - and thermal systems (thermoelectricity, Stirling engines, absorption processes), to meet end-use heating and cooling needs, and to recover waste thermal energy. The generic scientific approach proposed is based on a thermodynamic approach that meets common objectives focused on the energy efficiency of the systems studied.
