Band Model Parameters for the 4.3-microns Fundamental Band of CO2 in the 100-3000 K Temperature Range
Abstract
A set of band model parameters for CO2 in the 4.3-micrometer spectral region and consistent for the entire temperature range from near-ambient atmospheric temperatures (about 200K) to gas combustion temperatures (about 2500K) is constructed. This construction is accomplished by joining together band model parameters derived from the AFCRL atmospheric absorption line data compilation (LINAVECO2 parameters) and parameters tabulated in the NASA Handbook of Infrared Radiation from Combustion Gases (NASACO2 parameters). The former set adequately describes the low-temperature variations of the parameters, but is inadequate for high-temperature applications. The latter set is suitable for high-temperature applications, but fails for low-temperature cases. Examples of the deficiencies of these two sets are presented by comparison of predicted spectra with experimental absorption and emission spectra for low- and high- temperature gas samples. The adequacy of the combined band model parameter set (COMBCO2 parameters) is demonstrated by comparison with the same experimental data. Examples of the construction of the combined set are given, and a tabulation of the parameter set is included as an Appendix.
