APPROXIMATE EMISSIVITY CALCULATIONS FOR POLYATOMIC MOLECULES. 1. CO2 - AND APPENDIX

Abstract

Approximate emissivities were calculated at a function of optic al density for CO sub2 at 300 deg. and 600 deg. K under the assumption that the rotational lines overlapped extensively. The condition appeared to be satisfied at total pressures above 1 atm. The calculated values agreed with those of Hottel (Heat Transmission, chap. 3, McGraw-Hill, N.Y., 1942). The results showed that reasonable estimates of the engineering emissivity were obtainable without extensive analysis by adding the partial emissivities from selected spectral regions.
