Galerkin technique for radiative transfer in a plane-parallel medium

The radiative transfer through an inhomogeneous plane-parallel medium of an isotropic scattering with diffuse and specular reflecting boundaries is con sidered. The medium may be illuminated by a diffuse or collimated light and may have an internal energy source. The Galerkin technique is used to solv e this problem. The calculations are carried out for homogeneous and inhomo geneous media with isotropic or anisotropic scattering containing uniform o r nonuniform internal energy source. Comparison with other techniques are g iven whenever possible. (C) 1998 Elsevier Science Ltd. All rights reserved.
