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 کاملExperimental 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 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 کاملTurbulent jet flow generated downstream of a low temperature dielectric barrier atmospheric pressure plasma device
Flowing low temperature atmospheric pressure plasma devices have been used in many technological applications ranging from energy efficient combustion through to wound healing and cancer therapy. The generation of the plasma causes a sudden onset of turbulence in the inhomogeneous axisymmetric jet flow downstream of the plasma plume. The mean turbulent velocity fields are shown to be self-simil...
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...
