プラズマチューブ内における微粒子の撹拌および搬送特性

Abstract

The innovative technology is proposed for micro particle mixing and transportation in a plasma tube using electrostatic force coupled with plasma actuation on the inner surface of a tube. This Plasma tube (Dielectric Barrier Discharge tube) is composed of a pair of spiral electrodes both inside and outside of the tube for the generation of DBD. The fundamental characteristics of a plasma tube such as discharge characteristics and induced flow velocity were clarified experimentally. Furthermore, three dimensional electrical potential distribution as well as particle trajectory inside the plasma tube was shown by computational simulation.
