ABSTRACT
A conservative form of the discrete transfer radiation method (DTRM) has been applied in a computational fluid dynamics (CFD) simulation of the radiative heat transfer in an experimental furnace with complex geometry. The furnace was operated under nonpremixed conditions, burning preheated heavy fuel oil. For combustion simulation a semiempiric oil combustion model has been applied, while for the flow field resolution an unstructured CFD code has been used. The simulation results are compared with available experimental data, showing acceptable level of prediction accuracy. The conservative DTRM formulation is shown to be superior to the original formulation in this particular case.
