The Thermoelectric Effect Interface
The Thermoelectric Effect Interface
When the predefined Thermoelectric Effect () interface is added (found under the Heat Transfer branch () of the Model Wizard or Add Physics windows), it combines the Electric Currents and the Heat Transfer in Solids interfaces for modeling Peltier-Seebeck-Thomson effects. In addition, the Electromagnetic Heat Source, Thermoelectric Effect, and Boundary Thermoelectric Effect multiphysics couplings are added automatically.
The multiphysics couplings add the thermoelectric effect, the electromagnetic power dissipation, and the electromagnetic material properties, which can depend on the temperature.
Depending on the product license, stationary, time-domain, and frequency-domain modeling are supported in all space dimensions. In addition, combinations of frequency-domain modeling for the Electric Currents interface and stationary modeling for the Heat Transfer in Solids interface, called frequency-stationary and frequency-transient modeling, are supported.
On the Constituent Physics Interfaces
As a predefined multiphysics coupling, Electric Currents and Heat Transfer in Solids interfaces are added to the Model Builder. In addition, a Multiphysics node is added, which includes the multiphysics coupling features Thermoelectric Effect, Electromagnetic Heat Source, Boundary Thermoelectric Effect, Boundary Electromagnetic Heat Source, and Temperature Coupling.
The Electric Currents interface calculates the electric field, current, and potential distributions in conducting media under conditions where inductive effects are negligible; that is, when the skin depth is much larger than the studied device. Depending on the licensed products, time and frequency domain formulations that account for capacitive effects are also provided. The Electric Currents interface solves a current conservation equation based on Ohm’s law using the scalar electric potential as the dependent variable.
The Heat Transfer in Solids interface provides features for modeling heat transfer by conduction, convection, and radiation. A Solid model is active by default on all domains. All functionality for including other domain types, like a fluid domain, is also available. The temperature equation defined in solid domains corresponds to the differential form of the Fourier’s law that may contain additional contributions like heat sources.
