Abstract

Spectral transmittance and total band absorptance of selected infrared bands of carbon dioxide and water vapor are calculated by using the line-by-line and quasi-random band models and these are compared with available experimental results to establish the validity of the quasi-random band model. Various wide-band model correlations (such as Edwards and Balakrishnan, Tien and Lowder, and Felske and Tien) are employed to calculate the total band absorptance and total emissivity of these two gases under homogeneous and nonhomogeneous conditions. These results are compared with available experimental results under identical conditions. From these comparisons. it is found that the quasi-random band model can provide quite accurate results and is quite suitable for most atmospheric applications. Edwards and Balakrishnan, and Tien and Lowder correlations can provide reasonable results for homogeneous and nonhomogeneous conditions and, therefore, are useful for most engineering applications.
