“…An example of noise experienced in Q-V diagrams is shown in Figure 10, as well as Refs. [47,48]. The unfiltered plot in Figure 10 shows background noise during the capacitive phase, but larger spikes during the discharging phase of the DBD cycle.…”

Atmospheric Pressure Plasma - From Diagnostics to Applications

Atmospheric pressure dielectric barrier discharges (DBD) has many industrial applications and remains a focus of academic research. This chapter provides a thorough overview of electrical diagnostics for DBD, with a specific focus on charge-voltage measurement techniques. These methods are often underutilised in the existing scientific literature, despite the fact that they can provide useful insights into plasma behaviour. Both optimization of the electrical measurement setup and the interpretation of results are treated in-depth. The diagnostic techniques are discussed for a range of applications, from classic planar DBDs, to catalyst packed beds, plasma actuators, as well as techniques for measuring single microdischarges.

“…Research carried out by Patil et al shown a significant role of O 2 admixtures in the formation of NO x . For pulsed power supply, air mixtures were not only economically advantageous, but also allowed to obtain a lot of NO 2 that increased with increasing O 2 fraction [29]. Experiment on the sinusoidal and pulsed power supply for water spray GA carried out by Burlica and Locke has shown significant concentration of nitrates NO 3 − formed in water, when the working gases were air and N 2 , compared to very low levels obtained for Ar and O 2 .…”

The gliding arc discharge plasma reactors are known as a source of non-equilibrium plasma at atmospheric pressure. In the present study, generation of dominant reactive oxygen and nitrogen species in gaseous and liquid phase in water by the compact gliding arc device (mini-GAD) and corresponding bactericidal effects were investigated. Water and phosphate buffer solutions were used as model liquids. Mini-GAD is a strong source of nitrogen oxides (up to 800 ppm NO and 200 ppm NO 2) that result in high concentrations of nitrites and nitrates in water solutions. The highest bactericidal efficacy towards Escherichia coli was achieved for non-buffered water solution.

“…Besides this classical configuration, there are several other designs, addressing the need of specific optimization for specific applications, like for example discharges with multiple electrodes [3,4], a magnetically stabilized gliding arc (MGA) reactor [5], a reactor with vortex gas flow [6,7], etc. The GAD is very promising for various applications, such as CO 2 conversion [7,8], dry reforming of methane [9,10], N 2 fixation [11,12], surface treatment [13] and even waste treatment [14]. This type of discharge is attractive, because it allows the generation of relatively dense plasma in the order 10 20 -10 22 m -3 while sustaining a relatively low gas temperature below 2000-3000 K. Taking into account that the electron temperature in these discharges is in the order of 1-2 eV, it is clear that GADs produce thermally non-equilibrium plasmas, which are found to be preferable for various plasma assisted gas conversion processes [1].…”

In this work we study the energy transport in a gliding arc discharge with two diverging flat electrodes in argon gas at atmospheric pressure. The discharge is ignited at the shortest electrode gap and it is pushed downstream by a forced gas flow. The considered current values are relatively low and therefore a non-equilibrium plasma is produced. We consider two cases, i.e., with high and low discharge current-28 mA and 2.8 mA, and a constant gas flow of 10 L/min which has a significant turbulent component of the velocity. The study presents an analysis of the various energy transport mechanisms responsible for the redistribution of the Joule heating to the plasma species and the moving background gas. The objective of this work is to provide a general understanding of the role of the different energy transport mechanisms on the arc formation and sustainment, which can be used for the improvement of existing or new discharge designs. The work is based on a 3D numerical model, combining a fluid plasma model, the Shear Stress Transport Reynolds Averaged Navier-Stokes (SST RANS) turbulent gas flow model and a model for gas thermal balance. The obtained results show that at higher current, the discharge is constricted within a thin plasma column with several hundred of Kelvins above room temperature, while in the low current discharge, the combination of intense convective cooling and low Joule heating prevents discharge contraction and the plasma column evolves to a static non-moving diffusive plasma, continuously cooled by the flowing gas. As a result, the energy transport in the two cases is determined by different mechanisms. At higher current and constricted plasma column, the plasma column is cooled mainly by turbulent transport, while at low current and unconstricted plasma, the major cooling mechanism is energy transport due to non-turbulent gas convection. In general, the study also demonstrates the importance of turbulent energy transport in redistributing the Joule heating in the arc and its significant role for the arc cooling and the formation of the gas temperature profile. In general, the turbulent energy transport lowers the average gas temperature in the arc and thus it allows additional control of thermal non-equilibrium in the discharge.
