Predictions of the total band absorption are useful for describing the absorption process in calculations dealing with radiation interaction in absorbing-emitting liquids. Two two-parameter models, similar to the Elsasser and the statistical narrow band models used in gas radiation work, are developed for predicting the total band absorption in regions of the liquid CCl4 spectrum. The parameters, which are considered to be adjustable, can be determined from experimental total band absorption data or, if available, basic spectroscopic information. Results from the models are compared to experimental total band absorption measurements for CCl4 as well as a prediction based on spectral integration.

Total Emissivity

Hottel’s Rule and Penner’s Rule for estimating the total absorptivity of a homogeneous gas from a total emissivity chart or expression are generalized. The generalized rule is developed from an examination of the functional relationships between total and spectral molecular gas radiation properties. It gives a rational prescription for finding the absorptivity or emissivity at arbitrary pressure from the one-atmosphere total emissivity. Calculations of total properties from band absorption data correlations are used to find the needed map of pressure scaling exponent versus path-length-pressure product and gas temperature. Also addressed is the question of allowing for reflecting walls in the calculation of radiation heat transfer between a homogeneous gas and its enclosing walls. Both exact and high-accuracy-approximate calculations are shown to be possible using only total properties.
