Theoretical study of column of discharge with liquid non-metallic (tap water) electrodes in air at atmospheric pressure

Résumé

The discharge established between two liquid non-metallic electrodes (DLNME) is investigated. This d.c. discharge burns between two streams of tap water in open air at atmospheric pressure in diffuse form. In the plasma column two zones are defined: one close to the near-cathode and the other one close to the near-anode regions of the discharge. In each zone, the composition, massic enthalpy, volumetric emissivity of N2(2+) spectral band (376-380 nm), hydrogen spectral line (Hα) and triplet oxygen spectral lines (777 nm) have been calculated in non-equilibrium conditions. The comparison with experimental results allows determining the ratio between translational temperature of electrons and that of heavy species and an upper limit of the air humidity in both zones. This type of calculation describes satisfactorily the previously obtained experimental results
