“…Electrical discharges generated along the surface of water have also been investigated, particularly in the case of the flashover (see figure 2(D)) [64]. These devices are streamer discharges which propagate at the gas-liquid interface.…”

Plasma-liquid interactions represent a growing interdisciplinary area of research involving plasma science, fluid dynamics, heat and mass transfer, photolysis, multiphase chemistry and aerosol science. This review provides an assessment of the state-of-the-art of this multidisciplinary area and identifies the key research challenges. The developments in diagnostics, modeling and further extensions of cross section and reaction rate databases that are necessary to address these challenges are discussed. The review focusses on nonequilibrium plasmas.

“…Electrical discharges generated over a water surface have also been studied especially in the case of the so-called flashover of wet high voltage cables which are simulated by electrolyte baths (see figure 10(c)) e.g. [99]. Typical propagation velocities of this kind of discharge are in the range 1-10 km s −1 and depends on the resistivity of the water [100,101].…”

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.

“…Additionally, experiments, conducted by the authors [1], also suggest that increasing the water conductivity from 80 µS/cm to 1000 µS/cm decreases the breakdown voltage of such a system by around 10%. In [6] and [7], Rumeli built a mathematical model d=30 cm pixels=454 to calculate the flashover voltage along a water column, in which an equation for solving the resistance of a water column was proposed, and results were in a good agreement with the test results. However, it is found that a big difference occurs when employing this equation to calculate the breakdown voltage under test conditions employed here.…”

A breakdown model of rod-plane air gaps in the presence of water streams has been established. Water streams which do not fully cross air-gaps are considered. This model involves the breakup length and surface conductivity of a water stream, the stream's diameter, the number of the water droplets in the remaining air gap and the distance between two adjacent water droplets. The breakdown voltage is considered in two parts: one being the voltage drop along the water stream surface, and the other the voltage drop across the remaining air gap. To study the two components of voltage drop, the equivalent surface conductivity of a water stream and the voltage-current characteristics between two water droplets were investigated. Additionally, theoretical and experimental results are compared and it has been found that under the conditions considered, the breakdown voltages are predictable to within 13%. Evidence regarding the impact of radial dispersion of droplets and their distortion on the breakdown process is considered.
