Radiative transfer in highly scattering materials - numerical solution and evaluation of approximate analytic solutions

K. C. Weston, Albert C. Reynolds, A. Ali-Khan, D. W. Drago

Abstract

Numerical solutions for radiative transport in a class of anisotropically scattering materials are presented. Conditions for convergence and divergence of the iterative method are given and supported by computed results. The relation of two flux theories to the equation of radiative transfer for isotropic scattering is discussed. The adequacy of the two flux approach for the reflectance, radiative flux and radiative flux divergence of highly scattering media is evaluated with respect to solutions of the radiative transfer equation.
