Abstract
In this article, the finite-volume method is applied, in conjunction with the blocked-off-region procedure, to solve the radiative heat transfer problem in a three-dimensional partitioned rectangular enclosure containing absorbing-emitting and isotropic scattering medium in the presence of heat generation. Three-dimensional test cases were chosen to benchmark this model against other methods, namely, the discrete transfer method, the discrete ordinates method, and the zone method. For all cases, excellent agreement is obtained using reasonable spatial and angular discretizations. Then the radiative heat transfer problem is solved for an idealized furnace with a finite-thickness opaque partition. The shadowing partition effect is discussed for different optical medium properties and partition surface emissivities.
