Comparison between corona and dielectric barrier discharges plasma using of pin to single and dual ring electrodes configuration

Abstract

Research on one of the study plasma corona discharge and plasma dielectric barrier discharges (DBD) with positive polarity using the configuration of pin to single and dual ring electrodes has been done. The both discharge plasma generator used in this study was formed by stainless steel, pin electrodes as anodes and ring electrodes as cathodes. The diameter of pin was 0. 1 mm and diameter outside of single ring was 2.60 cm and insite 2.40 cm. For dual ring, we install other ring insite the big ring (with diameter outside was 2.60 cm). The scond ring, outsite diameter was 2.00 cm and insite diameter was 1.80 cm. Barrier of DBD reactor was made by dielectric material of glass with thickness of 3 mm with an area that can cover all ring electrodes. Characterization of the corona discharge plasma and the DBD Plasma were used to locate the respective working areas of the reactor. Variations of voltage used from 0 kV to arc with specified intervals of 0.2 kV, with variations of distance between electrodes were from 0.5 cm to 2.0 cm with intervals 0.5 cm. The result of I-V characterization shows the current produced by DBD plasma reactor was bigger than the corona discharge reactor and it follows the I-V quadratic law. Moreover, the value of unipolar ion mobility DBD plasma reactor were also greater than corona discharge reactor.
