| dc.description.abstract | Thermoelectric materials possess the unique ability to convert thermal energy into elec-trical energy and vice versa, making them ideal for tasks such as recovering lost heat and providing cooling. This thesis explores the modelling and investigation of the Pel-tier effect, a thermoelectric phenomenon that exhibits nonlinearity. The study used a one-dimensional (1D) finite element model. The primary objective is to observe the impact of the Peltier effect on thermoelectric temperature and voltage differences. Utilizing the Finite Element Method (FEM) for modelling thermoelectric materials al-lows for detailed analysis of their nonlinear behaviour. However, achieving accurate simulations necessitates incorporating these nonlinearities, often leading to computa-tional inefficiencies. This research addresses this challenge by employing Newton's method, a robust numerical technique known for its fast convergence, to solve the non-linear equations inherent in thermoelectric problems. The project involves developing a 1D finite element model in MATLAB, incorporating the nonlinearities of the Peltier effect. This model is validated against established tools such as ANSYS to ensure accuracy. The study's findings contribute to a better under-standing of nonlinear computational procedures in thermoelectricity and offer insights for constructing efficient 3D nonlinear finite element solvers. This work underscores the significance of numerical methods, particularly the combi-nation of FEM and Newton's method, in enhancing the accuracy and efficiency of ther-moelectric simulations. By addressing the nonlinearities directly, this approach aims to optimize the design and performance of thermoelectric devices, paving the way for in-novative applications in energy conversion and thermal management. | |
