| Research Abstract |
he innovative technology is proposed for nano particle mixing and transportation in a plasma tube using electrostatic force coupled with induced flow by dielectric barrier discharge on the inner surface of a tube. This DBD plasma tube is composed of a pair of spiral electrodes both inside and outside of the tube for the generation of DBD plasma. The fundamental characteristics of DBD 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 tube were shown by computational simulation. Furthermore, mist of methylene blue was introduced to plasma tube and it was successfully decomposed by ozone in a plasma tube.
