Original Abstract

In presented numeric model of nitrogen plasma, the vibration distribution function (VDF) was studied in time. About 90 % of total energy in plasma dissipated into vibration levels and changed to the electron excitation, ionization, dissociation and another processes. Thus more processes such as v-t, v-v, etc. were necessary to know for the calculation of VDF in time. First step was the simulation of v-t process for the collision of N_2 molecule with N_2 (X, v) on the computer. Subsequently, probabilities of the v-t transfer were calculated from the SSH theory at particular discharge conditions. Finally, the VDF model in time was calculated from the obtained transfer probabilities and initial concentrations in active discharge, but only for the v-t process. Population vibration levels in VDF were changing to the Boltzman distribution.
