Inside of a combustion chamber, the gas mix behaves as a non-gray medium. Such media require a lot of data and computational resources to get results across the whole spectrum. The Weighted Sum of Gray Gases Model (WSGG) proposes an approach to model the non-gray gas mix as a sum of abstract gray gases, which represents, in total, the behavior of the gas mix integrated over the whole spectrum.

This model presents the WSGG functionality available in the Radiation in Participating Media physics interface, applied with the Discrete Ordinates Method (DOM). The WSGG coefficients represent a mix of water (H2O) and carbon dioxyde (CO2) resulting from the complete combustion of methane (CH4) in presence of oxygen (O2). They are given in:
