Modelling and simulation of a thermoelectric structure with pellets of non-standard geometry and materials

• Characterization of a non-standard thermoelectric structure.
• Direct relation between thermoelectric properties and pellet material.
• Good correlation between simulation, experimental and computational results.
• Verification of good performance of the Finite Element Model used.

The aim of this paper is to develop and manufacture a thermoelectric structure operating in Peltier mode with non-standard materials, using a Finite Element Model. Thus, both the reliability of the Finite Element Model and the correct development and design of the new thermoelectric structure are ascertained, achieving a dual goal of our research group. This work provides a very good correlation between simulated and experimental results, and corroborates that the material's performance has a decisive influence on the thermoelectric properties of the structure in the temperature range of study considered.
