Approximate models for radiative transfer. (English) Zbl 1130.85006
Summary: We give a summary of the partial moment approach for radiative transfer, combined with a minimum entropy closure. This approach is a generalization of the moment approach. We review some well-established models, like the method of spherical harmonics, discrete ordinates, diffusion, higher-order diffusion and flux-limited diffusion. We present numerical examples, where different methods are compared.
