- 論文の詳細を見る
A new type of high power plasma jet were developed and its fundamental characteristics were clarified. High energy density plasma beam can be generated in a "gas tunnel" produced by a strong vortex flow with a high flow rate. And it can be ejected as a high power plasma jet from the torch. It is easier to obtain extremely high power plasma jet with this "gas tunnel type" than with the conventional type. The characteristics of the gas tunnel type of plasma jet are follows ; 1) high voltage, 2) high thermal efficiency, 3) high energy density.
