Total hemispherical emittances for CO2 or H2O including particulate scattering
Abstract
The total hemispherical emittance from a planar layer containing a spectrally absorbing gas and isotropically scattering particulate is determined. The exponential wide band model is used to represent the gaseous absorption while the optical path length concept is employed to include the effects of scattering. Total emittance values for either water vapor or carbon dioxide with particulate are presented. Numerous gas-scattering interactive effects and variable effects are identified and explained. A charted solution technique is presented which allows approximate yet accurate total emittance values to be obtained without calculation.
