Abstract

Relationship between barrier discharge characteristics and ozone generation under ac voltage application has been investigated for triple needles-plane configuration with two different needle-tip radii (r=l5, 80μm) in dry air. Characteristics of barrier discharge and ozone generation depend on the needle-tip radius. Especially, ozone concentration and ozone generation efficiency for the triple needles with r=80μm were higher than those for the needles with r=l5μm. These results can be interpreted by the effect of the space charges and accumulated charges induced by corona discharge and barrier discharge on the space for ozone generation
