Radiation transfer and photochemical transformations in a disturbed rarefied gas

Optical properties of non-equilibrium plasma, the radiation process, the kinetics of radiation-chemical processes in gases and plasma are investigated in the paper aiming at the automated system development for the calculation of radiation characteristics of non-equilibrium plasma, the numerical modelling of glows over surfaces of space vehicles during orbital flidhts and the early stage of powerful high-altitude explosions. As a result processes, responsible for the glow oveo space vehicles of various types have been investigated. Particles-radiators have been determined. The mathematical model of the early (photochemical) stage of the powerful high-altitude explosion in the Earth's atmosphere has been developed. Main laws have been established. The automated system for the calculation of radiation characteristics of non-equilibrium plasma for computers has been created. Matrix elements for transitions 110 (X II) have been determined as well as radiation coefficients for low-temperature (nitric) plasma. The calculation methodology for photochemical transformations and radiation transfer on the early stage of the powerful explosion in a rarefied gas has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
