Use the Heat Transfer with Radiation in Absorbing-Scattering Media multiphysics coupling (
) to account for heat transfer by conduction, convection, and radiation in semi-transparent (participating) media considered to be non-emitting. The radiative intensity equations are approximated either by the Discrete Ordinates Method or the P1 Approximation, depending on the
Radiation discretization method selected in the
Participating Media Settings section of the coupled Radiation in Absorbing-Scattering Media interface.
It adds the radiative heat source term Q (SI unit: W/m
3) to the heat transfer equation, defined by:
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
htrasm1.
Select the Heat transfer interface associated to the temperature dependent variable. Select the
Radiation in absorbing-scattering media interface associated to the radiative intensity variable (with Discrete Ordinates Method) or the incident radiation variable (P1 approximation).
