On Thursday, December 13, 2018, Julien RAMOUSSE, PhD student in energy and process engineering at the Laboratory for Design Optimization and Environmental Engineering (LOCIE), will defend his thesis entitled "Phenomenological modeling and thermodynamic analysis of energy conversion systems."
The defense will take place at 2 p.m. in room C104, Polytech Annecy-Chambéry building, on the Annecy campus.
Thesis summary
The current energy context calls for the implementation of innovative, highly efficient solutions that use resources that have been underutilized until now, with a view to achieving a realistic and sustainable energy transition. To address these issues, the work presented focuses on phenomenological modeling and thermodynamic analysis of different energy conversion systems in order to optimize their performance. The systems discussed can be classified into two categories: – electrochemical systems (PEMFC fuel cells and microbial fuel cells), which directly convert 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 heat energy. The proposed generic scientific approach is based on thermodynamics, with a focus on the common objectives of energy efficiency for the systems studied.
