要約(英語): In this research, concentrations of hydrogen peroxide and dissolved ozone generated by direct current plasma within oxygen bubbles in water were measured. The current magnitude and water conductivity were changed from 1 to 7mA, and from 1 to 100 μS/cm, respectively. The highest efficiency of hydrogen peroxide generation was 0.64g/kWh at 7mA with 100μS/cm solution. The concentration of dissolved ozone decreased with increasing the discharge current, and was almost zero when the current was higher than 5mA. Non-dimensional simulation revealed that the water vapor concentration in bubbles strongly affects the generation of active species. With a large current, the amount of water vaporized into the bubbles enlarged due to a large heat flux from plasma.
