- Аннотация: Results from numerical investigations of kinetic processes initiated by a pulsed nanosecond discharge in hot (T0 ≥ 1000 K) air at atmospheric pressure are presented. The calculated results on the dynamics of the electron density, the population of the N2(B3Πg) and N2(C3Πu) states, and the atomic oxygen density in the axial discharge region agree with experiment. The method for determining the gas temperature by measuring the rotational structure of the transitions N2(C3Πu, v) → N2(B3Πg, v') of the 2+ nitrogen system is analyzed. It is shown that, in relatively weak reduced electric fields typical of secondary discharge pulses, the electron impact excitation of the N2(C3Πu) state from the ground state N2(X1Sig) can be accompanied by its additional step population from the N2(B3Πg), N2(a'Sig), and other electronic states. This effect substantially influences the rotational distribution of nitrogen molecules in the N2(C3Πu,v) state; moreover, the temperature determined from this distribution can be substantially higher than the true gas temperature.
