THE USE OF DATABASE FOR PHYSICOCHEMICAL PROCESSES IN FORMULATION OF SETS OF EQUATIONS GOVERNING A CHEMICALLY REACTING AND VIBRATIONALLY RELAXING GAS

A universal generator of equations that describe physicochemical kinet ics using databases comprising chemical and plasma-chemical reactions, vibration-vibrational and vibration-translational energy exchange bet ween various modes in molecules, and processes allowing for the effect of chemical reactions on vibrational relaxation is developed. A mathe matical model of physicochemical processes in mixtures containing CO2, N-2, He, H2O, CO, O-2, H-2, NO, OH, H, and O molecules and atoms is s uggested, a mechanism of vibrational energy exchange and chemical reac tions is chosen, and a physicochemical database is compiled. Potential ity of the generator is illustrated by way of example of numerical sim ulation of kinetic processes taking place in flows of a CO2-containing laser mixture in a supersonic nozzle and laser cavity.
