放電下における液膜内部流動および界面挙動の実験解析

抄録

Interaction of atmospheric pressure plasma with a liquid film was investigated in order to understand a transport mechanism of chemically reactive species generated by the atmospheric pressure plasma in a liquid. The atmospheric pressure plasma produces a gas flow known as an ion wind. It has been reported that the ion wind induces the flow in the liquid. In our research, micro bubbles were generated in a liquid film under a streamer discharge. The internal flow was visualized using the micro bubbles as tracer particles. The micro bubbles were moved toward a discharge point on the liquid film edge under the streamer discharge. The micro bubbles were moved toward the grounded electrode in a corona discharge regime. The chemically reactive species generated by the atmospheric pressure plasma were detected in an optical emission spectra.
