Dual frequency DBD: influence of the amplitude and the frequency of applied voltages on glow, Townsend and radiofrequency DBDs

Plasma Sources Science and Technology, 2020
Abstract To study dual frequency Townsend glow and radio frequency DBDs in an Ar/NH 3 Penning mixture, different voltages are applied on each electrode of a plane/plane DBD. The one which has the higher amplitude and frequency, V H

Energy contribution in a DBD reactor

2008 IEEE 35th International Conference on Plasma Science, 2008
Summary form only given. Dielectric barrier discharge (DBD) reactors are widely used for such as ozone generation and pollution controls. The energy injected into a DBD reactor is used expectantly to generate ions, energized electrons, radicals and excited atoms/molecules to yield a non-thermal plasma.

Investigation on a DBD Plasma Reactor

IEEE Transactions on Plasma Science, 2011
This paper investigates the effect of some dielectric barrier discharge plasma reactor parameters such as dielectric conductivity and electrode gap on the plasma mode. The results show that in the shorter gap, plasma is more homogenous, and dielectric conductivity can affect on the plasma mode.

Pulsed DBD at atmospheric pressure

The 31st IEEE International Conference on Plasma Science, 2004. ICOPS 2004. IEEE Conference Record - Abstracts., 2004
Summary form only given. Dielectric Barrier Discharges (DBDs) are traditionally driven by sinewave voltages with magnitudes in the kV range and frequencies in the kHz range. Depending on the operating parameters, DBDs can generate either filamentary or diffuse plasmas.

The Experimental Study on Ozone to Remove NO by DBD

2011
In order to study the reduction efficiency of NO with Ozone produced by dielectric barrier discharge (DBD). The NO removal experiments with different O2 flow were performed. As a result, the NO removal rate changed little with discharge power at different concentration of O2.

One dimensional simulation of microscale DBD plasma

10th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2015
An one dimensional multi-fluid plasma model is setup for micro-scale DBD plasma device. The micro-scale DBD plasma device has an inverted pyramidal cavity with metal-dielectric-metal structure. The features of Ar micro-plasma generated in micro-DBD device are numerical simulated through COMSOL software.

Distribution of surface electric charge in a surface DBD

2012 Abstracts IEEE International Conference on Plasma Science, 2012
Summary form only given. For more than one decade, the surface dielectric barrier discharge (SDBD) has been extensively studied in aerodynamic applications as electro-hydrodynamic (EHD) actuators [1]. The SDBD was also largely studied for air pollution treatment due to the lower discharge ignition voltage and the larger contact surface with catalyst ...

Stimulating living cells with air DBD plasma

MRS Proceedings, 2012
ABSTRACTCells positioned at the bottom of a Petri dish were exposed, in a home-made plasma source, to pulsed Dielectric Barrier Discharges operated in air in order to investigate the effect of the plasma species on their viability and growth. Processes with different number of pulse, respectively 1,3,9 and 27 pulse, were performed to study the ...

Biomethane reforming in DBD nonequilibrium plasma

2012 Abstracts IEEE International Conference on Plasma Science, 2012
Summary form only given. There are several publications claiming to describe production of hydrogen from biogas using plasma-catalyst systems1. However, the authors has used a mixture of methane with carbon dioxide simulating a biogas but without any additives which are present in real biogas such as water vapour, H 2 S and NH 3 .

DBD modification of polyethylene powder hydrophobicity

Czechoslovak Journal of Physics, 2006
Problems of the powder particles plasma modification are practically the same as in the case of solid films. Troubles of the powder treatment are related with its three-dimensional character, small size of particles, treated large area and problems with powder manipulation, that also must not be neglected.
