“…A question arises as to what mechanism is responsible for this self-organization. Another question is to what extent are these patterns similar to self-organized patterns observed on solid [11][12][13][14][15][16][17][18][19][20][21][22] and liquid [23,24] cathodes of dc glow discharges. An additional interest in the physics of self-organization on anodes of glow discharges has developed recently, when it has been shown that self-organized patterns on liquid anodes of atmospheric pressure glow microdischarges reveal a nontrivial cancer-inhibiting capability [25].…”

Self-organized patterns of spots on a flat metallic anode in a cylindrical glow discharge tube are simulated self-consistently. A standard model of glow discharges is used, comprising conservation and transport equations for a single species of ion and electrons, written with the use of the drift-diffusion and local-field approximations, and the Poisson equation. Only processes in the near-anode region are considered and the computation domain is the region between the anode and the discharge column. Multiple solutions, existing in the same range of discharge current and describing modes with and without anode spots, are computed for the first time. A reversal of the local anode current density in the middle of each of the spots was found, i.e. mini-cathodes are formed inside the spots or, as one could say, anode spots operate as a unipolar glow discharge. The solutions do not fit into the conventional pattern of self-organization in bistable nonlinear dissipative systems; e.g. the modes are not joined by bifurcations.

“…The most common discharge ignition schemes are implemented when a metal electrode is immersed in an electrolyte [8], or when the metal electrode is located at some distance from the electrolyte surface [9]. The ambient air pressure used in the studies is limited to the range of 10 5 −10 3 Pa, since at lower pressures the solution begins to boil in the electrolytic cells of the gas discharge chamber.…”

The work is devoted to the study of the characteristics of a low-temperature plasma of a high-frequency (HF) discharge (f=13.56 MHz) ignited between metallic and electrolytic electrodes at atmospheric pressure. Burning of an RF discharge in a diffuse (volumetric) form is observed at the interface between the media between the electrodes. Numerical calculations of the electric field strength and the distribution of the volumetric power density of the Joule heat release before breakdown in a vapor-gas mixture near a metal electrode are presented. The discharge radiation spectrum, plasma composition, and electron density were studied by optical emission spectroscopy. The thermograms of the electrode surface under the conditions of an RF discharge are considered. Keywords: Plasma-liquid systems, high-frequency discharge, electrolytes, numerical methods.

“…Зажигание разряда осуществляется в газоразрядных камерах с различными типами и формами конфигурации электродов, включающие в себя системы: твердый−жидкий электроды [2][3][4][5], жидкий (проточный)−жидкий (непроточный) электроды [6], жидкий (проточный)−жидкий (проточный) электроды [7]. Наиболее распространенные схемы зажигания разряда осуществляются при погружении металлического электрода в электролит [8], либо при расположении металлического электрода на некотором расстоянии от поверхности электролита [9]. Давление окружающего воздуха, используемое при проведении исследований, ограничивается диапазоном 10 5 −10 3 Pa, так как при более низких давлениях начинается кипение раствора в электролитических ячейках газоразрядной камеры.…”
