Integrated Electrical, Spatial, and Thermal Characterization of Atmospheric-Pressure Ar–O₂ Plasma Jets with Ag and Cu External Ring Electrodes
Atmospheric-pressure plasma jets (APPJs) require coordinated control of electrical excitation, gas flow, plume propagation, and thermal output to operate at controlled low temperatures. This study presents an integrated electrical and physical characterization of two geometrically identical Ar–O₂ APPJ systems employing...
