摘要:In this work, the atmospheric-pressure dielectric barrier discharges in Ar and N-2 excited by repetitive voltage pulses have been numerically studied using a 1D fluid model. The differences between the discharge characteristics for Ar and N-2 have been presented when changing the parameters of the applied pulse voltage. In this work we present the following significant results. With an increase of the amplitude of the applied pulse voltage, the increase of the maximum discharge current density in Ar is evident, compared with N-2; and the discharge mode changes from the weak atmospheric-pressure glow discharge (APGD) to the standard APGD for Ar, and from the atmospheric-pressure Townsend discharge to the APGD for N-2. In addition, the increase of the averaged electron density in N-2 is more evident than that in Ar, especially when the standard APGD occurs in N-2. The increasing frequency leads to lower maximum discharge current density for Ar, however, the reverse is true for N-2. With an increase of the pulse width of the applied pulse voltage, the averaged electron density and the maximum discharge current density change slightly in Ar, but they increase drastically in N-2.
