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
