Resumo

A numerical procedure for solving combined-mode heat transfer problems in radiatively participating media based on the finite element method and discrete exchange factor methods is presented. This technique is suitable for analysis of combined conduction, convection, and radiative transfer problems. Comparisons with earlier published results of conductive/radiative heat transfer in a rectangular enclosure display the good accuracy of the proposed method. In addition, the flexiblity of the method is illustrated via temperature calculations in irregular configurations, including: a right-triangular enclosure (displaying mesh refinement in local regions) and a rectangular enclosure with a circular hole at its center (involving blocking between direct radiative exchange regions).
