Decomposition of dichlorobenzene in a dielectric barrier discharge
Environmental Technology, 2011This paper presents a decomposition study of 1,2-dichlorobenzene (DCB) using a dielectric barrier discharge (DBD). The discussion is focused on the effects of variations of carrier gases, DCB concentrations and input voltages on the decomposition performance.

Vibration of Discharge Filaments in a Dielectric Barrier Discharge
IEEE Transactions on Plasma Science, 2014The vibration of discharge filaments in a concentric spotring pattern in a dielectric barrier discharge is investigated by high-speed camera. The pattern, consisting of several sparsely and densely arranged-spot rings, bifurcates from a vibrating hexagonal superlattice.

Decomposition of dimethylamine gas with dielectric barrier discharge
Journal of Hazardous Materials, 2013The decomposition of dimethylamine (DMA) with gas under high flow rate was investigated with dielectric barrier discharge (DBD) technology. Different parameters including removal efficiency, energy yield, carbon balance and CO2 selectivity, secondary products, as well as pathways and mechanisms of DMA degradation were studied.

Destruction of Formaldehyde with Dielectric Barrier Discharge Plasmas
Environmental Science & Technology, 1995Destruction of formaldehyde (HCHO) molecules via dielectric barrier discharges (DBDs) is experimentally investigated in this study. HCHO is chosen due to its ubiquitous existence, potential health hazards, and chemical form. Destruction of HCHO molecules can be achieved by both «direct electron attack» and «indirect gas-phase radical reaction ...

Experimental determination of dielectric barrier discharge capacitance
Review of Scientific Instruments, 2012The determination of electrical parameters (such as instantaneous power, transferred charge, and gas gap voltage) in dielectric barrier discharge (DBD) reactors relies on estimates of key capacitance values. In the classic large-scale sinusoidal-voltage driven DBD, also known as silent or ozonizer discharge, capacitance values can be determined from ...

Square superlattice pattern in dielectric barrier discharge
Physical Review E, 2006We report the observation of a square superlattice pattern in a dielectric barrier discharge system. The correlation measurements indicate that the square superlattice pattern is an interleaving of two different transient square sublattices. The interplay between the charge pattern and the discharge filament pattern is discussed.

Honeycomb hexagon pattern in dielectric barrier discharge
Physical Review E, 2007We report on a honeycomb hexagon pattern in dielectric barrier discharge. It bifurcates from a square pattern as the applied voltage is increased. A phase diagram of the pattern types as a function of the gas component and applied voltage is presented.

Applications of dielectric barrier discharges
12th International Conference on High-Power Particle Beams. BEAMS'98. Proceedings (Cat. No.98EX103), 2002Dielectric barrier discharges (DBDs) in oxygen and air are well established for the production of large quantities of ozone and are more recently being applied to a wider range of plasmachemical processes. As an introduction of this type of gas discharge, the main plasmaphysical features of sinusoidal-driven DBDs (transient, non-thermal plasmas at ...

Numerical simulation of surface dielectric barrier discharge
2016 IEEE International Conference on Information and Automation (ICIA), 2016In order to better study and reveal the discharge mechanism and evolution of the dielectric barrier plasma generator, in this paper, the discharge in atmospheric argon is simulated by 2D numerical method. From the discharge particle chemical reaction of Ar and Ars electronic, it can be obtained that the relationship between the particle concentration ...

Hexagonal superlattice state in dielectric barrier discharge
Physical Review E, 2006We report on the observation of a hexagonal superlattice state (HSS) in dielectric barrier discharge in air/argon near atmospheric pressure. It bifurcates directly from the hexagonal state by increasing the applied voltage. The correlation measurements indicate that the HSS is an interleaving of three different transient sublattices.
