“…As the surface plasma grows in the direction of the anode, numerous branches fan-out from the main discharge, as the frame for t = 100 ms shows. These branches resemble the watersurface Lichtenberg figures observed in [6]. However, most of these branches tend to be short-lived, with the exception of those which lie along the axis of the trough in the direction of the submerged anode.…”

A type of plasma discharge that propagates along the surface of a resistive barrier composed of an electrolyte in water is described. Electric fields parallel to the surface appear to steer the discharge in the direction of a submerged anode to produce a propagating plasma front that travels a distance of 20 cm or more along a trough, at a rate of ∼10 ms −1 . The plasma's optical spectrum shows the presence of excited OH radicals, and the relatively high energy density of the plasma indicates possible usefulness for industrial applications.

“…Research in this field is, however, quite phenomenological. Belosheev [102][103][104][105] studied leader propagation on water surfaces. He found that there was a oneto-one correspondence between the channel lengths and the currents flowing in them during the discharge.…”

During the last two decades atmospheric (or high) pressure non-thermal plasmas in and in contact with liquids have received a lot of attention in view of their considerable environmental and medical applications. The simultaneous generation of intense UV radiation, shock waves and active radicals makes these discharges particularly suitable for decontamination, sterilization and purification purposes. This paper reviews the current status of research on atmospheric pressure non-thermal discharges in and in contact with liquids. The emphasis is on their generation mechanisms and their physical characteristics.

“…In this case, the discharge is not in direct contact with the liquid surface. In the case of corona or spark discharge directly over the water surface where the streamer channel propagates along the surface of the water, the water conductivity has an important role in the nature of the discharge channel propagation, the channel length and current are directly related, and UV light is also produced. − …”

The application of strong electric fields in water and organic liquids has been studied for several years, because of its importance in electrical transmission processes and its practical applications in biology, chemistry, and electrochemistry. More recently, liquid-phase electrical discharge reactors have been investigated, and are being developed, for many environmental applications, including drinking water and wastewater treatment, as well as, potentially, for environmentally benign chemical processes. This paper reviews the current status of research on the application of high-voltage electrical discharges for promoting chemical reactions in the aqueous phase, with particular emphasis on applications to water cleaning.
