Finite element analysis of coupled heat conduction and enclosure radiation
Many important problems in heat transfer involve conducting solids containing enclosures or cavities within which radiation interchange occurs. A numerical procedure for the analysis of this type of coupled radiative-conductive heat transfer is presented. The procedure presented here is based on the finite element method which allows for problems with arbitrary geometries and arbitrary radiative and conductive properties. The procedure does not require that temperature or radiative flux be assumed constant over each surface segment but allows them to vary according to the finite element basis functions. The procedure also accounts for the mirror effect of planes of symmetry which pass through enclosures when such planes are utilized to reduce the size of the numerical problem.
