Detailed Description

This boundary condition provides a grey-diffuse condition for radiation intensity, I, for use with the finite-volume discrete-ordinates model (fvDOM), in which the radiation temperature is retrieved from the temperature field boundary condition.

An external radiative heat flux can be added using qRadExt. If qRadExtDir is specified, this ray closest to this direction is used. Otherwise, the face normal is used as direction to set qRadExt.

Usage
Example of the boundary condition specification: 
<patchName>
{
    // Mandatory entries
    type            greyDiffusiveRadiation;

    // Optional entries
    T               T;
    qRadExt         <scalar>;
    qRadExtDir      <vector>;

    // Inherited entries
    ...
}

where the entries mean:

Property Description Type Reqd Deflt
type Type name: greyDiffusiveRadiation word yes -
T Name of temperature field word no T
qRadExt Radiative external flux scalar no Zero
qRadExtDir Radiative external flux direction vector no Zero

The inherited entries are elaborated in:
