Conducting region with double heat exchange (3D)

Conducting region with double heat exchange

In thermal applications there can be a specific type of region, a conducting region with double heat exchange that enables the modeling of thin conducting regions with thermal exchanges on both faces.

This region is a combination of:

a thin conducting region (a material region)
two heat exchange surfaces (non-material regions)

Definition and conditions of use

The definition and the conditions of use of the Conducting region with double heat exchange are presented in the table below.

The region…	enables the modeling…
conducting with double heat exchange ( + heat source )	of a conducting medium (thermal conductivity k volumetric heat capacity ρC_P)
with thermal exchanges on both sides (by convection / radiation)
with possibly a heat source (= thermal power), (uniform or space dependent)

conducting with double heat exchange

( + heat source )

of a conducting medium

(thermal conductivity k volumetric heat capacity ρC_P)

with thermal exchanges on both sides

(by convection / radiation)

with possibly a heat source (= thermal power),

(uniform or space dependent)

The thermal flux by conduction is assumed to be tangential to the surface region.

Note: *the radiation of the “thin conducting region with double exchanges and thermal source” is equivalent to the radiation to infinite of the regions with one side radiation, with adding the Kirchhoff law (emissivity coefficient equal to the absorption coefficient).

Note: A surface region of the Conducting region with double heat exchange type should have thermally inactive neighboring volume regions, or no neighboring volume regions.
