摘要

Radiative intensity in 6,658 and 281 directions in the hemispheric space was provided by the distribution of ratios of energy scattered by the medium or reflected by the boundary surface method (DRESOR) at the boundary of a two-dimensional enclosure filled with isotropic and anisotropic scattering medium, respectively. The dimensionless radiative heat flux achieved by the DRESOR method agreed well with those by other methods in the literature. Besides the polar angle, the intensity at the boundary varies significantly with the azimuthal angle, especially for the points close to the emitting source. In the anisotropic scattering media, the largest boundary intensity occurs with the largest forward scattering capability.
