Abstract
Plasmas generated at gas-liquid interface have been developed for water treatment. Reactive species, such as H202, 03, and OH radical, are mainly generated in the gas phase, and then transfer to the liquid phase. In this study, zero-dimensional numerical simulation of reactions in gas and liquid phases and the mass transfer through the gas-liquid interface was conducted for plasma generated inside oxygen bubbles. Comparison between the numerical and experimental results quantitatively revealed the reaction paths and phenomena at the plasma-liquid interface such as water vaporization due to the heat flux from the plasma to the water.
