Abstract: Approximate equations for radiative heat transfer equations coupled to an equation for the temperature are stated and a comparative numerical study of the different approximations is given. The approximation methods considered here range from moment methods to simplified PN-approximations. Numerical experiments and comparisons in different space dimensions and for various physical situations are presented.

Keywords: radiative transfer; SPN-approximations; moment methods; frequency averages; discontinuous coefficients.
