摘要：

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 P-N-approximations. Numerical experiments and comparisons in different space dimensions and for various physical situations are presented.
