摘要
We experimentally determined the characteristics of atmospheric-pressure glow discharge (APGD) produced by pin-plate electrodes with a gas flow between the electrodes. APGD is sustained by applying a DC voltage between the electrodes with main and auxiliary air flows. The auxiliary air flow is added to the main flow in a localized region using a small nozzle. It is found for the first time that glow discharge current significantly increases when the auxiliary nozzle is set near the anode plate. By adding only 6% of the main flow as the auxiliary air flow, the maximum current of APGD increases threefold that in the case without the auxiliary flow.
