The present study investigates the arc behavior and temperature distribution in a water plasma with mist generation under different mist feeding rates. The arc fluctuation was observed using a high-speed camera with arc voltage measurement. Further, the arc temperature was visualized by a high-speed video camera and band-pass filters based on the Boltzmann plot method. The experimental results showed that the arc fluctuation was in the restrike mode, and the frequency as well as the arc length apparently increased with an increase of mist feeding rate due to stronger drag force. Higher arc existence probability was also observed. At the same time, the mist feeding rate played an important role in controlling the arc area with high temperature. This study will open up new opportunities for waste treatment by understanding the fundamental arc characteristics in a water plasma system.
