Abstract
An atmospheric plasma discharge was produced between a platinum pin electrode and the surface of water. The thermal flow field of the cold atmospheric plasma in air and water was measured experimentally and analyzed computationally. A gas flow with a velocity of around 15 m/s was shown to be generated toward the water surface by the discharge. This air flow induced a circulating flow in the water from the discharge point at the water surface due to friction. These results were also predicted computationally.
