Research on Electrical Characteristics of Dielectric Barrier Discharge and Dielectric Barrier Corona Discharge

Japanese Journal of Applied Physics, 2012
The dielectric barrier corona discharge (DBCD) in a wire-cylinder configuration and the dielectric barrier discharge (DBD) in a coaxial cylinder configuration are studied. The discharge current in DBD has higher pulse amplitude than in DBCD. The dissipated power and the gas gap voltage are calculated by analyzing the measured Lissajous figure. DBCD has

Efficiency enhancement of a dielectric barrier plasma discharge by dielectric barrier optimization

Review of Scientific Instruments, 2010
The characteristic feature of a dielectric barrier discharge (DBD) is the dielectric barrier placed between the electrodes. In the present work, the influence of the dielectric barrier to the properties of a DBD in air was investigated. Spectroscopic characterization of the DBD and electrical measurements were carried out.

Dynamics of dielectric micropore discharge in atmospheric pulsed dielectric barrier discharge

Physics of Plasmas, 2023
In this paper, a two-dimensional self-consistent fluid model was developed in atmospheric helium for dielectric barrier discharge excited by microsecond voltage pulses, in which a dielectric sheet with micropore is inserted in the interelectrode gap.

Asymmetric discharges of dielectric barrier discharge in atmospheric air

Applied Physics Letters, 2023
We report in this Letter a kind of asymmetric discharge mode in positive and negative half-cycles of dielectric barrier discharge in ambient air. This phenomenon is characterized by homogeneous and filamentary discharges occurring alternately in the two half-cycles, using two different materials of alumina ceramic and quartz as the dielectric barrier ...

Vibration of Discharge Filaments in a Dielectric Barrier Discharge

IEEE Transactions on Plasma Science, 2014
The 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, 2013
The 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, 1995
Destruction 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, 2012
The 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 ...
