Abstract

This paper presents a new computational procedure for computing the spectral absorption coefficient of CO2, CO, H2O, CH4, C2H2, and NO. The procedure is based on a combined narrow- and wide-band model which gives the absorption coefficient as a function of radiation wavelength, temperature, total pressure and partial pressure of the gases. The average line spacing is the only correlation parameter that is adjusted to fit integrated band absorptance data. Results show that the accuracy of the present procedure is comparable to those obtained from using different correlations. A positive feature of the present procedure is, however, a single model that is applicable to all the gases considered.
