Characteristics of Ozone Jet Generated by Dielectric-Barrier Discharge

The characteristics of ozone jet generated by atmospheric-pressure coaxial dielectric-barrier discharge has been experimentally clarified through the visualization of discharge and also by the measurement of ozone concentration for various operating conditions, such as applied voltage, frequency, and gas flow rate. It is shown that the ozone production is highly controllable with applied voltage, and 1500 ppm of ozone can be produced at the input power as low as 72 W.
