Elasto-thermoelectric beam formulation for modeling thermoelectric devices

Abstract: The present paper provides a dynamic, non-linear and fully coupled Finite Element (FE) formulation based on the Timoshenko beam theory to study elasto-thermoelectric responses in thermoelectric devices. The two main motivations of this work are: i) to study mechanical responses in thermoelectric devices, which must be taken into account in the design of Peltier cells due to the fragility and relative low strength of the semiconductors , and ii) to provide a numerical tool that decreases the CPU time to allow t… Show more

“…Furthermore, this method is optimal for applying to nonlinear coupled problems as thermoelectricity. In this connection, the authors of the present chapter have extensive experience in developing thermodynamic consistent FE formulations, which are implemented in the research code FEAP [20], see [21][22][23][24][25] and [26]. Regarding commercial FE codes, the authors in [27,28] use ANSYS to perform a comprehensive numerical analysis focusing on the cooling performance of miniaturized thermoelectric coolers for microelectronics applications.…”

“…On the contrary, the Extended Nonequilibrium Thermodynamics (ENET) [11] incorporates a viscous-like term to the fluid phase, which could explain the frequencydependence of the cervix. For instance, R. Palma et al have developed analytical and numerical solutions to study the second sound in thermoelasticity (see [12,13]), which can be considered as a viscothermal effect. Also, ENET is applied in [14] to study the Debye relaxation: a viscoelectric effect.…”
