• SLW

To investigate non-gray combined conduction and radiation problems, this paper uses the FVM to solve the energy equation and radiative transfer equation and the SLW method to model the effect of gas spectral properties in a 2D geometry. Carbon dioxide, water vapor and carbon monoxide are considered as the participating media. The effects of gas species, gas mixture ratios and wall emissivities on the temperature and heat flux were investigated. The accuracy of the gray gas model is also analyzed compared to the SLW method.
