Acoustic Testing of the dielectric barrier discharge (DBD) plasma actuator
43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005The dielectric barrier discharge (DBD) plasma actuator has been shown to be effective for flow control. Much remains unanswered, however, as to how the actuator couples momentum into air. A better understanding of the coupling mechanism is crucial to determining the performance limitation of the actuator and the breadth of applications to which it can ...

Discharge analysis and electrical modeling of a coaxial dielectric barrier discharge (DBD) lamp
2008 IEEE 35th International Conference on Plasma Science, 2008Dielectric barrier discharges (DBDs) occur by the presence of at least one insulating layer in contact with the discharge between two planar or cylindrical electrodes connected to an AC or pulse power supply. Dielectric barrier discharge (DBD) consists of filamentary micro-discharges under nonequilibrium, atmospheric pressure plasma condition.

Deposition of fluorocarbon polymer films in a dielectric barrier discharge (DBD)
Surface and Coatings Technology, 2003Abstract Investigations of an intermittent dielectric barrier discharge in fluorocarbon mixtures at atmospheric pressure are reported. Plasma diagnostics were performed by FTIR-absorption spectroscopy as well as by emission/absorption spectroscopy in the UV/VIS range. Deposited polymer films were investigated by FTIR absorption spectroscopy, XPS, SEM

Surface Modification of Fluororubber Using Atmospheric Pressure Dielectric Barrier Discharge (DBD)
Plasma Science and Technology, 2007Fluoride rubber F2311 film, an alternating copolymer of CF2-CFCl (CTFE) and CH2-CF2 (VF2) components, was treated by atmospheric pressure dielectric barrier discharge (DBD) in air. The surface structure, topography and surface chemistry of the treated F2311 films were characterized by contact angle measurement, atomic force microscopy (AFM), and X-ray ...

Dielectric Barrier Discharges (DBD) in Gases at Atmospheric Pressure: Effect of Charge Trapping
2005 12th International Symposium on Electrets, 2006We present theoretical modeling of atmospheric pressure discharges in air and helium where one of the electrodes is covered by a dielectric (dielectric barrier discharge, DBD), as well as ultra-high speed imaging studies for the case of He. It is found that charge on the dielectric barrier surface strongly influences the characteristics of individual ...

Abstract Ca0.7Sr0.3TiO3 was sintered adding Li2Si2O5, and used as a dielectric barrier of DBD to decompose CO2 for the first time. DBD plasma was successively generated using Ca0.7Sr0.3TiO3. CO2 was converted to CO and O2 by DBD plasma without catalyst and reducing substance.

Surface acid chemistry associated with dielectric barrier discharge (DBD) treatment of polyethylene
Plasma Sources Science and Technology, 2006The chemistry associated with atmospheric dielectric barrier discharges (DBDs) in air has been studied. Laboratory and industrial DBD systems have been investigated. In this work, we have emphasized the use of aqueous extractions of treated surfaces, followed by analyses by ion chromatography to study the DBD chemistry. A range of DBD factors including

Abstract A new procedure for determining the characteristic capacitance of DBD plasma actuators during operation is introduced, based on time-resolved discharge cyclograms. The actuator performance is described extensively and the interaction of several key quantities is elucidated. Operating voltage and corresponding power consumption are identified
