誘電体バリア放電を用いた狭小空間内でのイオン風発生の検討

抄録

Ionic wind generation in the narrow gap was investigated. In this study, dielectric barrier discharge (DBD) was used to generate ionic wind. The electrodes for wind generation were composed of 0.9 mm or 0.12 mm thick dielectric plate made of Pyrex glass, and 0.1 mm thick aluminum tape as discharge and ground electrodes. 13.5 kHz and 6 kV_pp ac high voltage with 2.3 kV dc bias was applied to the discharge electrodes. Two of such the electrodes were faced each other with distances ranged from 0.5 to 1.8 mm and the wind velocities in the space were investigated. Wind velocity more than 1.0 m/s was obtained in case where the electrodes distance was 0.5 mm with the dielectric plate of 0.9 mm thick, while less velocities were found with the dielectric plate of 0.12 mm thickness.
