Аннотация:Fast gas heating is studied experimentally and numerically in pulsed nanosecond capillary discharge in pure nitrogen and N2 : O2 mixtures at conditions of high specific deposited energy (up to 1 eV/molecule) and high reduced electric fields (E/N = 100-300 Td). Deposited energy, electric field and gas temperature are measured as function of time. Radial distribution of active species is analyzed experimentally. The roles of process involving N2(B)= N2(B3Пg; W3Su; B'3Su), N2(A3Su) and N(2D) excited nitrogen species leading to heat release are analyzed using numerical modeling at 1D axial approximation.
