Description

Strong emission in liquid is observed by radio frequency irradiation using a submerged electrode. Plasma is generated in liquid, and because the liquid around the plasma is evaporated instantly, the plasma seems as if to be generated in a bubble. We measured the spectrum of the plasma emission, analyzed the produced gas by plasma in water and also measured the production rate of hydrogen gas. The mole ratio of hydrogen to the produced gas is 90 to 99% and the rate of hydrogen gas is 1.2 to 2.3 larnol/s at 150 W. The rate of the hydrogen gas decreases with increase of the pressure from 60 to 100 kPa. To clarify the gas production mechanism, we carried out numerical simulations of the chemical reactions inside and outside the bubble. As a result, the mole ratio of the produced gas is .approximately agreeable to the experimental result.
