Non-gray radiation study of gas and soot mixtures in one-dimensional planar layer by DRESOR

A SNBCK/DRESOR combined method is presented in order to predict the radiative heat transfer of gas and soot mixtures at different temperature configurations. The mixtures of the combustion gases (H2O, CO2, CO) and the different soot loadings were analyzed to explore the influence of the soot on the non-gray radiation. The radiative source and the intensities with high directional resolution calculated by the DRESOR method were investigated at different temperature configurations. The accuracy of the SNBCK/DRESOR model was also analyzed and compared to the LBL/DOM approach, where the relative errors were less than 4%. The results indicate that the SNBCK/DRESOR method has a better efficiency than the SNBCK/DOM method. (C) 2018 Elsevier Ltd. All rights reserved.
