Abstract

This paper presents the evolution of striated discharge patterns in helium and argon atmospheric-pressure plasma jets as a function of gas flow rate and driving voltage. The striated patterns have been observed in helium and argon plasma jets at gas flow rates above 5 and 3 L/min, respectively. The striation patterns appear over the entire voltage range used for investigation (from 4 to 8 kV) in the helium plasma jet, whereas in the argon plasma jet, striation patterns appear over a limited voltage range (from 5.5 to 6.5 kV).
