Abstract

Radiative transfer in an absorbing and isotropically scattering two-layer medium around an opaque cylinder is considered. Numerical solutions of the integral equations of radiative transfer are obtained by the collocation method; differential approximation solutions are obtained by the spherical harmonics method. For most of the cases considered, reasonably accurate results can be obtained by using a four-term expansion for the integral equation method. The hemispherical-hemispherical and hemispherical directional reflectivities of the medium exposed to diffuse radiation are presented. The effects of radius ratios, optical thicknesses and scattering albedos on the reflectivities are investigated. The outer layer of the medium has a great influence on the reflectivities.
