To obtain large-volume non-thermal arc plasma (NTAP),a multiple NTAP generator with three pairs of electrodes has been developed.The arc plasma characteristics,including dynamic process,spatial distribution,and rotation velocity in the discharge zone,were investigated by high speed photograph and image processing methods.The results showed that the dynamic behaviors and spatial distribution of the arc plasma were strongly related to the electrode configuration.A swirl flow of multi-arc plasma was formed by adjusting the electrode configuration,and a steady luminance area was clearly observed in the center of the discharge zone.Moreover,the size of the luminance area increased by decreasing the gas flow rate.The electrical connection in series could be formed between/among these arc columns with their respective driving power supplies in the multi-arc dynamic evolution process.An approximately periodical process of acceleration and deceleration of the arc rotation velocity was observed in the multi-arc generator with swirl flow configuration.In general,the mean velocity of arc rotation was higher in the multi-arc generator with swirl flow configuration when a pair of electrodes driven by a power supply were opposite to each other rather than adjacent.
