    Numeric Modelling of V-T Process in Nitrogen Ground State under Post-Discharge Conditions

  • Original language description

    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.

    Numerické modelování V-T procesu v základním stavu dusíku za podmínek dohasínání

  • Czech description

    Numerický model dusíkového plazmatu studuje vibrační distribuční funkci (VDF) v čase. Okolo 90 % energie v plazmatu se rozděluje do vibračních hladin základního stavu a dále se srážkami přerozděluje během dohasínání. Proto je při výpočtu VDF v čase je potřeba znát více procesů jako v-t či v-v procesy Prvním krokem byla počítačová simulace v-t procesu pro kolizi molekul dusíku N_2 s N_2 (X, v). Následně byly spočítány pravděpodobnosti v-t přechodu podle SSH teorie.
