Radiative transfer in three-dimensional rectangular enclosures
Abstract
Radiative transfer in a three-dimensional rectangular enclosure containing radiatively participating gases and particles is studied using the spherical harmonics approximation. Inhomogeneities in the radiative properties of the medium as well as in the radiation characteristics of the boundaries are allowed for. The scattering phase function is represented by the delta-Eddington approximation and it is assumed to be a function of the location to account for density variation of the particulates in the medium. Numerical solution of the model equations is obtained by using a finite difference scheme. Results are compared with those based on the Hottel's zonal method for the purpose of validating the approximation.
