Summary:Three kinds of electrode configurations are employed for studying the spurt length of atmospheric-pressure plasma jets (APPJs). The influences of Ar flow rate, applied voltage, and electrode width on APPJ length are investigated. It is found that, for all the electrode configurations, the maximal length of the APPJ is achieved at 3 L/min of flow rate. With the increase of the applied voltage, the length of the APPJ increases and gradually tends to saturation. Furthermore, the APPJ propagation turns shorter under a wider wrapped electrode. It is considered that the variation of the APPJ length is attributed to the combination effects of Ar flow status, the amount of high-energy particles at the ionization front, and the memory effect of charges on dielectric surfaces.
