A line-by-line calculation of low-resolution radiative properties of CO2-CO-transparent nonisothermal gases mixtures up to 3000 K

Low-resolution radiative properties (absorptivities, transmissivities, intensities) of nonisothermal or inhomogeneous gas mixtures at high temperatures, suitable for radiative heat transfer applications (e.g., in combustion) are obtained from a line-by-line calculation, using recently published high-resolution spectroscopic data at 296 K given by AFGL. It is shown that absorptivities obtained for isothermal mixtures of CO₂, CO, N₂ (and sometimes H₂O) agree with the corresponding measured spectra.
