Self-organized patterns by a DC pin liquid anode discharge in ambient air: Effect of liquid types on formation

A pin liquid anode DC discharge is generated in open air without any additional gas feeding to form self-organized patterns (SOPs) on various liquid interfaces. Axially resolved emission spectra of the whole discharge reveal that the selforganized patterns are formed below a dark region and are visible mainly due to the N2 (C 3 -B 3 ) transitions. The high energy N2 (C) level is mainly excited by the impact of electrons heated by the local increased electric field at the interface. For the first time, the effect of the liquid type on the SOP formation is presented. With almost the same other discharge conditions, the formed SOPs are significantly different from HCl and H2SO4 liquid anodes. The SOP difference is repeated when the discharge current and gap distance change for both liquid anodes. The variations of SOP size and discretization as a function of discharge current and gap distance are discussed and confirm that different SOPs are formed by the HCl liquid anode from tap water or the H2SO4 liquid anode. A possible explanation is brought up to explain the dependence of SOPs on the liquid type. Effect of liquid types on formation, S. Zhang, T.

“…Perturbations often initiate the switch from a uniform anode glow to spots. 8 In air the reduced current density on the anode spot remains constant when the pressure is varied in the range from 8 to 60 Torr, and its value is equal to 0.27 mA/cm 2 Torr 2 . 11 But the anode fall therewith increases with pressure and it is much more prominent than that in the electropositive nitrogen discharge plasma.…”

An analytic model for a three-component electronegative plasma has been developed within the framework of a diffusion-drift approximation. Anode fall voltage and anode sheath thickness are found for elevated-pressure glow discharge. The predicted voltage-current dependencies are compared to available experimental and numerical results for dc glow discharges in air at pressures of 40-100 Torr. Electronegative ions increase the anode fall voltage at high current densities, including the values for anode spots, and reduce the anode fall voltage at low current densities, but pass through a minimum at a critical value of their concentration.
