Vibrational nonequilibrium radiation in diatomic gases. I, II
Abstract
The equations of radiative transfer in a nonequilibrium radiating heteronuclear diatomic gas are derived on the basis of a complete set of kinetic equations for the dynamics of an arbitrary molecular gas with allowance for radiation processes. Simplifying assumptions are made. The superpositional harmonic oscillatorrigid rotator approximation is used to describe quantum properties of molecules. First it is assumed that local thermodynamic equilibrium conditions are fulfilled in vibrational and transitionalrotational degrees of freedom separately. Approximate methods are developed for the nonequilibrium case. In particular, a diffusion approximation is given.
