The effect of different mesh size scales in prediction radiative heat transfer

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.A brief review of Multiscale Radiative Exchange Method (MREM) is presented and the method is applied to some 2D benchmarks. Within the computational frame of this method, radiative heat transfer in different mesh structures with wide range of optical thicknesses is predicted The predictions of radiative heat transfer in finer mesh structures are applied in the calculation of radiation heat transfer in the coarser ones. The results obtained by this method showed a good conformity with previously reported results. The method provides a fast and accurate way fur simulation of radiative heat transfer in large­-scale industrial combustion equipments.
