Three-dimensional transient radiative transfer modeling using the finite-volume method

This article presents a finite-volume method to calculate transient radiative transfer in a three-dimensional enclosure. The fully implicit scheme is used to discretize the transient term. The step and CLAM spatial differencing schemes are used in this study. The procedure is validated using available published results. The ability of the present formulation in modeling an absorbing, emitting and isotropically scattering medium is examined using heat fluxes and incident radiation. Ray effect and false scattering are discussed.
