Simulation Calculation of the Surface Dielectric Barrier Discharge Characteristic Parameters Under Nanosecond
摘要
Abstract
In order to better understand the discharge mechanism of the surface dielectric barrier discharge and illustrate the regularity evolution of characteristic parameters of the plasma,an equivalent circuit of the asymmetric surface dielectric barrier discharge plasma generator is established based on the experimental results of electrical and optical diagnostics of surface dielectric barrier discharge.The parameters such as the discharge current and electron density acquired by the equivalent circuit model are fitting well with the experimental data,which proves the effectiveness of this model.Firstly,the variation of air gap voltage,voltage drop across the discharge gap,electron density,electron temperature,were calculated.Moreover,the influence of the slope of the power supply on the discharge parameters mentioned above is analyzed.It is shown that under the effect of the nanosecond discharge,there exists the second discharge under the rising edge and the reverse discharge under the falling edge,and the electron density and electron temperature are 2.7×1018 m-3 and 8.3 eV.The slope of the power supply takes important part in the discharge.As the voltage rate of rise is increased,the discharge occurs earlierand the current in the first discharge increases but the second discharge current decreases slightly.The increase of the voltage rate of decrease is positive correlation with the second discharge,but the first discharge current decreases slightly.关键词
