Abstract

DRESOR(distributions of ratios of energy scattered or reflected) method was applied to solve the radiative transfer equation for anisotropic scattering media with black boundary emission.Comparing the results with the existing exact solution,radiative element method,the Monte Carlo method and the finite volume method,it is shown that the results of DRESOR method are reliable.Furthermore,the intensity with high directional resolution in any point was obtained by DRESOR method.Also,the radiative transfer equation for the emitting,absorbing,anisotropic scattering gray media with diffusely boundary condition was solved and the results of radiative intensity and radiative flux was analyzed for different cases.
