Effects of Vibrational Nonequilibrium on the Chemistry of Two-Temperature Nitrogen Plasmas

摘要: A new two-temperature chemical kinetics model for nitrogen plasmas is presented. The used together with the vibrationally-specific collisional-radiative to study effects of vibrational nonequilibrium distributions on composition atmospheric pressure plasmas. It found that over a wide range conditions levels follow Boltzmann and temperature Tv well approximated by gas Tg at low electron number densities Te high densities. This result suggests simple kinetic models rate coefficients can be reliably nonthermal calculation also yields surprising that, given constant temperature, steady-state density exhibits an S-shaped dependence temperature. behavior caused competing ionization, charge transfer reactions, two-body dissociative recombination, three-body recombination therefore characteristic molecular
