Theoretical 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 کاملStudy on Discharge Dynamics in an Atmospheric Pressure Dielectric Barrier Discharge
In this work, the discharge dynamics in an atmospheric pressure dielectric barrier discharge (DBD) is studied in a DBD reactor having parallel plate electrodes geometry. The DBD reactor is powered by a 50 Hz ac high voltage power source through a ballast resistor. The images of filaments occurring in the discharge gap are captured using a high speed intensified charge coupled device camera. The...
متن کاملAtmospheric pressure plasma of dielectric barrier discharges*
The dielectric barrier discharge (DBD) has a number of industrial applications and has been a subject of research for many years. Many studies have been carried out to understand the underlying DBD physics. Despite the fact that much progress has been made, some important issues are still far from being clear. In this work, we summarize the basics of DBD physics and introduce innovative concept...
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 کاملPrediction of nested complementary pattern in argon dielectric-barrier discharge at atmospheric pressure
A two-dimensional self-consistent fluid model was employed to investigate the spatiotemporal nonlinear behavior in an argon glow-like/Townsend-like dielectric-barrier discharge (DBD) at atmospheric pressure. The discharge is characterized by a major current pulse with a residual one ahead per half cycle of the external voltage. The two current pulses are operated in glow mode, but with Townsend...
