Use the Thermoelectric Effect multiphysics coupling (
) to account for a Peltier heat source or sink in domains and on boundaries where electrical and thermal models are defined.
In domains, a PJ contribution is added to the heat flux
q in the equation for heat transfer in solids:
The term Je = −σS∇T is also added to the current density, which is then defined as:
On boundaries, a PsJ contribution is added to the heat flux
q in the equation for heat transfer in shells:
The term Je,s = −σsSs∇tT is also added to the current density, which is then defined as:
The Label is the default multiphysics coupling feature name.
The Name is used primarily as a scope prefix for variables defined by the coupling node. Refer to such variables in expressions using the pattern
<name>.<variable_name>. In order to distinguish between variables belonging to different coupling nodes or physics interfaces, the
name string must be unique. Only letters, numbers, and underscores (_) are permitted in the
Name field. The first character must be a letter.
The default Name (for the first multiphysics coupling feature in the model) is
tee.
From the Selection list, choose the domains where thermoelectric effect should be applied. Only domains where both electrical and thermal models are active can be selected.
From the Selection list, choose the boundaries where thermoelectric effect should be applied. Only boundaries where both electrical and thermal models are active can be selected.
Select the Heat Transfer interface associated to the temperature dependent variable. Select the
Electromagnetic interface associated to the electric potential dependent variable.
The Seebeck coefficients S and
Ss (SI unit: V/K) in the domain and on the boundaries should be set.
when any of the following interface is added together with Heat Transfer in Solids (or another version of the Heat Transfer Interface):
