ABSTRACT
This paper presents the computation of radiative heat transfer in a 2D axisymmetric enclosure using the WSGG model to compute radiation in a media composed of H2O, CO2 and soot. The WSGG correlations are based on HITEMP2010 database. Test cases consider typical conditions found in sooting flames, with steep variations in the temperature field and in the species concentrations. To assess the accuracy of the WSGG method, the results are compared with a solution obtained with the line-by-line (LBL) integration of the spectrum.
