The combined Monte-Carlo and finite-volume method for radiation in a two-dimensional irregular geometry

Abstract This article proposes a combined procedure of the Monte-Carlo and finite-volume method (CMCFVM) for solving radiative heat transfer in absorbing, emitting, and isotropically scattering medium with an isolated boundary heat source. The conventional flux methods such as the finite volume and the discrete ordinate methods are known to be afflicted by the ray effects due to its own angular discretization. Thereby, a wiggling behavior in the solution used to take place. In order to tackle this problem, which is especially pronounced in a medium with an isolated heat source, the CMCFVM is suggested here and successfully applied to a two-dimensional irregular enclosure.
