Study on the High-Intensity Free-Burning Arc and Aerodynamic Disturbances

다국어 초록 (Multilingual Abstract)

A scientific understanding of the high-intensity free-burning arc is critical for improving the
industrial applications of atmospheric plasma systems. However, it has not been easy to investigate
the characteristics of this arc theoretically and experimentally due to several problems such as the
interactions of electric, magnetic, fluid dynamic, and thermal effects. Furthermore, fluid dynamic
effects induced by the arc itself are important when the cathode jet impinges on the anode, resulting
in the well-known bell shape of free-burning arcs due to the flow stagnation, and when a metallic
probe is inserted to the flowing thermal plasma for the diagnosis. In this study, computer simulations
are presented for an entire free-burning arc with a metallic probe and for two different distances
between the cathode tip and the anode surface.
