Abstract in another language

In many energy conversion processes, thermal energy is released to the environment; that is, it remains unused. With the aid of thermoelectric generators (TEGs), a part of this energy can be converted into electrical energy. The efficiency of the process can be increased and the CO2 emissions are therefore reduced. In this contribution, the simulation and the design of a new concept of thermoelectric generator are discussed. The TEG is built ribbonlike and is wrapped around an electrically insulated tube, which is heated by waste heat from the inside and cooled by water from the outside. A numerical model is developed to theoretically study this concept. The goal is to understand the characteristics of the TEG and with it achieve a performance-optimized TEG design. In order to achieve the optimal design, parameter studies were carried out with the numerical model, which should help to determine the performance of the TEG. Geometrical dimensions, thermal resistance, and electrical resistance in the components are taken into account to accurately model the modules. The convective heat transport was taken into consideration in the study of the heat transfer as it plays a major role in the later application. Furthermore, the temperatures and heat flows are also studied as small changes of these can often have a direct impact on the system.
