Abstract
A multi-phase AC arc plasma has been applied in the glass melting technology as a promising heat source. In this work, the high-speed video camera system with appropriate band-pass filter was applied to investigate arc phenomena based on electrode temperature measurements synchronized with vapor observation during the arc. The results show that lower argon gas flow rate leads to larger electrode evaporation, resulting in the constriction of the arc. Correlation between arc phenomena and electrode phenomena in multi-phase AC arc was then investigated.
