Description
Summary:This paper deals with the modelling of materials and devices in which electric and thermal effects and their cross effects (thermoelectric effects) are important. A phenomenological model based on the thermodynamics of irreversible processes (TIP) and its mixed-hybrid finite-element implementation are presented. It is argued that TIP provides a unified approach to sensor modelling. Mixed-hybrid finite elements are used to resolve the thermoelectric interaction terms accurately. A numerical test example is given to demonstrate the feasibility of this approach.
