Emission of Radiation from Diatomic Gases. III. Numerical Emissivity Calculations from Carbon Monoxide for Low Optical Densities at 300 deg K and Atmospheric Pressure.

摘要

The general problem of emission and absorption of radiation involves two essentially distinct parts. One part of radiant heat transfer investigations is concerned with the determination of intensities if emissivities, absorptivities, and scattering coefficients are known. These studies are restricted to the problem of radiative transfer. For any defined geometric arrangement the radiative transfer problems can be formulated without difficulty. An exhaustive account of this work may be found in a recently published book by Chandrasekhar. The other part of the general problem is the determination of emissivities, absorptivities, and scattering coefficients, which enter into the radiative transfer calculations. Until very recently, practical applications have been based almost entirely on the use of empirically determined emissivities. jg p.1.
