Reaction Kinetics of Active Species from an Atmospheric Pressure Plasma Jet Irradiated on the Flowing Water Surface Effect of Gas-drag by the Sliding Water Surface

摘要

We performed numerical simulations for investigating atmospheric pressure humid air chemistry triggered by metastable argon atoms fed from an atmospheric pressure plasma jet (APPJ) irradiated on a flowing water surface. We discuss the gas-drag effect caused by the flow of water surface. The gas-drag effect may alter spatial profiles of gas-phase species around the APPJ. It may alter also spatial profiles of the flux of active species impinging on the water surface. The numerical simulations have revealed that the flux profile of OH radicals is surely altered by the gas-drag effect and its flux on the surface is reduced to 1/6 of that on the static surface.
