Transient radiative transfer in irregular two-dimensional geometries

This article presents a finite-volume method to calculate transient radiative transfer in two-dimensional irregularly shaped enclosures. 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 with available published results. The capabilities of the procedure are then examined using two additional test problems. The ability of the present formulation in modeling absorbing, emitting and anisotropically scattering media is examined using wall heat fluxes and incident radiation.
