Main project: Development and charactrisation of a Fe2VAl-based transverse thermoelectric module built by additive manufacturing
Funding: UCLouvain
Supervisor(s): Pascal Jacques

The aim of my thesis is to study and optimise an innovative alternative to classical thermoelectric generators according to different aspects : geometry, materials and manufacturing processes. More specifically, it consists in implementing and optimising a Fe2VAl-based transverse thermoelectric generator with an optimize internal topology built by multimaterial additive manufacturing. The main scientific issues that will dictate the experimental approaches and the modelling steps consist in : (i) understanding the transverse thermoelectric effect and its experimental study coupled with a topological optimisation (since existing studies are mainly theoretical only); (ii) the analyse of the microstructural characteristics resulting from the additive manufacturing on the electrical and thermal properties of the Fe2VAl compound (what has not been done so far), but also of the other compounds that are needed in case of multimaterial additive manufacturing; (iii) optimising the characteristics of a functional transverse thermoelectrical generator in function of the operating conditions.
