THERMAL RADIATION PHENOMENA. VOL. 4 EXCITATION AND NON-EQUILIBRIUM PHENOMENA IN AIR
Abstract
The report deals with excitation and non-equilibrium phenomena in air that has been subjected to a large amount of radiation. The following topics are covered: Absorption and scattering of X-rays and gamma rays in air; Collisions of ions and electrons with air molecules; Secondary processes following this excitation. (This includes the creation of various chemical species); X-ray heating and shock heating of air with special reference to very high energy densities; The approach to composition equilibrium in low and high temperature air; Adiabatic, near equilibrium cooling of air and the formulation of a criterion for local thermodynamic equilibrium; Non-equilibrium radiative transport and its effect on the total amount and the spectrum of emitted radiation; Radiation in tennous air at high temperatures; Radiation in tennous air with contaminants at low temperatures. The report has two appendices. One discusses mathematical aspects of the approach to equilibrium of a displaced system. The other one presents a table of the states and spectra of the metallic monoxides. (Author)
