Characteristics of Dielectric Barrier Discharge Reactor for Material Treatment
This work reports the development of atmospheric pressure plasma reactor with dielectric barrier discharge DBD for material treatment. The DBD discharge has been generated in planar geometry reactor powered by ac voltage provided by conventional high voltage transformer. The dielectric barrier consisted of two glass slabs, which cover both reactor electrodes. The air discharge gap between the d...
متن کاملA Numerical Study of the Sour Gas Reforming in a Dielectric Barrier Discharge Reactor
In this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. CH4, CO2, and H2S, to the various charged particles and syngas in a dielectric barrier discharge (DBD) reactor is studied. An electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. Based on the space...
متن کاملSurface Decontamination by Dielectric Barrier Discharge Plasma
Background: Dielectric barrier discharge (DBD), a source of non-thermal plasma, is used in surface decontamination. Objective: To study the effect of DBD plasma treatment, we evaluated the effect of plasma exposure time on inactivation of Bacillus subtilis. Results: Applying the DBD plasma to the culture of B. subtilis caused complete sterilization of the surface without any thermal effects. In...
متن کاملCharacteristics of Ozone Generated from Dielectric Barrier Discharge Plasma Actuators
Abstract—Dielectric barrier discharge plasma actuators (DBD-PAs) have been developed for active flow control devices. However, it is necessary to reduce ozone produced by DBD toward practical applications using DBD-PAs. In this study, variations of ozone concentration, flow velocity, power consumption were investigated by changing exposed electrodes of DBD-PAs. Two exposed electrode prototypes ...
متن کاملCharacteristics of a radio-frequency micro-dielectric barrier discharge array
Micro-dielectric barrier discharges (mDBDs) are known for being stable, high-pressure and non-thermal plasma sources. mDBD arrays consist of micro-plasma devices (10–100μm) in which the radio frequency (rf)-excited electrodes are covered by dielectrics. In certain applications, independent control of individual mDBDs in an array is required for charge extraction to treat dielectric surfaces. Wh...
