Abstract
Heat radiation solution of multimode heat transfer problems involving radi- ation is discussed. Two cases are analyzed: (i)radiation contributes to the boundary condition of steady state or transient heat conduction in opaque solids forming self irradiating cavities, (ii) a volumetric energy generation term due to heat radiation appears in the energy transfer equations in semi transparent solids or fluids. Heat radiation problems addressed encompass transparent and emitting-absorbing media. The solution of the radiation problems is by the BEM. Heat conduction is solved using BEM while the heat convection problems are discretized by the finite volume technique. The coupling conditions linking radiation with other heat transfer mode
