Abstract

A collocation spectral method (CSM) based on discrete-ordinates equation is employed to solve three dimensional radiative transfer equation (RTE) in an absorbing, emitting and scattering medium. Numerical results by the CSM are compared with those of discrete ordinates method (DOM) and benchmarks. These comparisons indicate that the CSM is more accurate than DOM.
