Multigroup half space moment approximations to the radiative heat transfer equations ?
The half space moment approximation to the radiative heat transfer equations developed in [J. Comp. Phys. 180 (2002) 584] for frequency-independent absorption and scattering is extended to frequency-dependent coefficients using averaging over frequency groups. We compare numerical results obtained with this new model to known approximations in different physical regimes.
