▲ [18a-234A-5] Effect of Power Source and Alcohol Addition on Atmospheric Plasma Jet Properties
キーワード：atmospheric pressure plasma jet, alcohol addition
For industrial application, running cost of current plasma jet is not economical and reduction of plasma production cost is still an important issue. In this study, alcohol addition effects were investigated with pure argon or argon-ethanol mixture gas in our low frequent discharge device.
Discharge characteristic was modified with small amount of alcohol addition. So-called plasma flame becomes shorter with alcohol and charged particle (electron) distribution along jet axis is also shorter. Plasma heat flux distribution along jet axis was, however, found to become larger. Necessary electrical power, which is specific to the used power source, is also affected by alcohol addition.
