Heat Transfer Equation in Participating Media
Heat flux in gray media is defined by
Heat flux divergence can be defined as a function of
G
and
T
(see
Ref. 20
):
In order to couple radiation in participating media, radiative heat flux is taken into account in addition to conductive heat flux. Recalling
Equation 4-16
, the heat transfer equation reads:
and is implemented using following form:
