Experimental Study of Low-Pressure Nitrogen Dielectric Barrier Discharge
The electrical and spectral characteristics of a dielectric barrier discharge (DBD) are experimentally investigated in a sealed off coaxial cylinder filled with nitrogen at a pressure of 10 mbar. The discharge is a transient diffused glow at low frequency alternating voltage (60 Hz) and changes to a filamentary mode at high frequency alternating voltage (35 kHz). In case of pulsed voltage, the ...
متن کاملStudy of Nitrogen Dielectric Barrier Discharge at Near and Over Atmospheric Pressure by Optical Emission Spectroscopy
To achieve suitable conditions for generation and observation plasma at over-atmospheric pressures we constructed a specially adapted reactor. Plasma was generated between two parallel electrodes covered by dielectric material. Observations were made in the dynamic mode (gas flow 1.4 l/min.) and static mode at pressures form 0.8 atm. to 2 atm. (from 0.9 atm. to 1.3 atm. in static mode) in high ...
متن کاملTheoretical study of the dielectric barrier discharge at atmospheric pressure
In this paper, the progress in the theoretical study of the dielectric barrier discharge is reported. The model of the atmospheric-pressure discharge is discussed. Such effects as the oscillations of the Townsend mode of the discharge, the instability of the Townsend mode with subsequent transition to the filamentary discharge, and the stabilization of the barrier discharge by the photoemission...
متن کاملExperimental Study of an Atmospheric Pressure Dielectric Barrier Discharge and PET Surface Modification
A homogeneous dielectric barrier discharge (DBD) in argon was produced by applying high voltage A.C. source of potential difference (0-20) kV operating at a frequency of 10-30 kHz across two parallel plate electrodes with glass as dielectric barrier. The discharge was characterized by optical emission spectroscopy (OES) and electrical measurement. Four argon emission lines from the discharge we...
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...
