| Coupled conduction and radiation heat transfer problems were solved using the based-cell and the finite volume method (FVM) in the regions with the mediums. The combined heat transfer equations were discretized in the unstructured meshes and the calculating programs were written. The radiative heat source of the combined equation was treated specially. Meanwhile, from the relations of the governing equations and the several of medium characters, the dimensionless numbers were obtained and computed using unstructured quad grids in various parameters, such as, optical thickness τ, conduction-radiation parameter N, and scattering albedo ω. |
