Electrically tunable thermal conductivity and exhaust heat recovery applications of thermoelectric materials

The current work is focused on two areas related to thermoelectricity: (i) the study of the capability of controlling the thermal conductivity of TEMs and (ii) the development, testing and improvement of an automotive thermoelectric generator (ATEG).The first part of the thesis proposes a novel appr...

Descrição
Resumo:The current work is focused on two areas related to thermoelectricity: (i) the study of the capability of controlling the thermal conductivity of TEMs and (ii) the development, testing and improvement of an automotive thermoelectric generator (ATEG).The first part of the thesis proposes a novel approach to the use of thermoelectric couples, treating them as variable insulators in thermal systems.The second part of this investigation is focused on exhaust heat recovery development. In the first place, author describes a method to help ATEG design and to predict its performance in terms of fuel economy
