大気圧誘電体バリア放電における蓄積電荷密度の時空間分布

抄録

Effect of secondary electron emission coefficient on accumulated charge density distributions in atmospheric pressure dielectric barrier discharges have been simulated using two dimensional fluid model. Spatio-temporal distributions of accumulated charge density on each side of dielectric have been examined. The differences of conventional waveforms of accumulated charge density and the simulated results were clarified. And when the dielectrics were negatively accumulated, charges were uniformly accumulated, while positive charges were not. Randomness of streamers occurrence, and self-organized structures have been also examined by the accumulated charge distributions.
