AIR RADIATION GRAPHS: SPECTRALLY INTEGRATED FLUXES INCLUDING LINE CONTRIBUTIONS AND SELF ABSORPTION
Abstract
Calculations have been made of the equilibrium radiation emitted from air over a range of temperatures from 2,000 degrees K to 23,000 degrees K and over a density range from 10 to the -6th to 10 atmospheres. The calculations are presented in graphical form and are in terms of the radiation flux emitted from one side of infinite slabs of finite thickness. The molecular band systems have been calculated using a smeared rotational model, and are carried out for a slab thickness of 1 cm. Atomic line and free-bound transitions are important contributors at elevated temperatures and also generally undergo significant amounts of self-absorption. Consequently calculations for these two classes of radiation have been made with slab thickness as an added parameter. The lines, free-bound and free-free radiation have also been split into the two spectral regions for the radiation flux above and below 2000 A.
