Effects of Control Parameters on Plasma Bullet Propagation in a Pulsed Atmospheric Pressure Argon Plasma Jet

Effects of control parameters (applied voltage, duty cycle, and gas flow rate) on the propagation of plasma bullets are investigated in a pulsed atmospheric pressure argon plasma jet. Images of plasma bullets in the voltage rising and falling phases are presented. The applied voltage, pulse duration, and gas flow rate are observed to influence the bullet propagation characteristics.
