Abstract
Gliding arc discharge is one of the unique plasmas of which the dynamic behavior is extremely complex in time and space. In this work, we report on time-resolved dynamic behavior of gliding arc discharge plasma in He and Ar using comparison of obtained results between high-speed camera (54 000 fps) photographs and the corresponding electrical properties. Both measurements were synchronized via an external trigger. For a gliding arc discharge in Ar 20 L/min, gliding of serpentine plasma was observed due to turbulent gas flow and reconnections of plasma path were observed. It was revealed that the applied voltage was decreased and small pulsed current flowed at the moment of the reconnection.
