摘要：

The effects of feed gas flow rate and operating current on the electrical characteristics and dynamic behavior of a rotating gliding arc (RGA) plasma codriven by a magnetic field and tangential flow were investigated. The operating current has been shown to significantly affect the time-resolved voltage waveforms of the discharge, particularly at flow rate = 2 1 min(-1). When the current was lower than 140 mA, sinusoidal waveforms with regular variation periods of 13.5-17.0 ms can be observed (flow rate -21 min(-1)). The restrike mode characterized by serial sudden drops of voltage appeared under all studied conditions. Increasing the flow rate from 8 to 12 l min(-1) (at the same current) led to a shift of arc rotation mode which would then result in a significant drop of discharge voltage (around 120-200 V). For a given flow rate, the reduction of current resulted in a nearly linear increase of voltage.
