Characteristics 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 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 کاملEffect of Dielectric and Liquid on Plasma Sterilization Using Dielectric Barrier Discharge Plasma
Plasma sterilization offers a faster, less toxic and versatile alternative to conventional sterilization methods. Using a relatively small, low temperature, atmospheric, dielectric barrier discharge surface plasma generator, we achieved ≥ 6 log reduction in concentration of vegetative bacterial and yeast cells within 4 minutes and ≥ 6 log reduction of Geobacillus stearothermophilus spores withi...
متن کاملInfluence of NO Concentration on Removal Efficiency in Multipoint-to-Plane Electrode Dielectric Barrier Discharge Reactor
An influence of initial nitrogen monoxide (NO) concentration on removal efficiency with a multipoint-to-plane electrode dielectric barrier discharge (DBD) reactor was investigated experimentally. Several hundreds ppm NO was diluted with nitrogen and oxygen gas mixture (N2:O2=9:1) and was fed to the DBD reactor as a diesel exhaust simulated gas. The experimental results were evaluated using a si...
