Investigation on Atmospheric Pressure Plasma Jet Array in Ar

An atmospheric pressure plasma jet linear array consisting of five jet units is developed; the influences of applied voltage amplitude, frequency of the power supply, and Ar flow rate on its characteristics are investigated using lighting emission images. The results show that the length and shape of the jet array vary with variation in these parameters, and the optimum operation conditions for the maximum length jet array are at applied voltage of 8.5 kV, frequency of 20 kHz, and gas flow rate of 20 L/min.
