摘要
为探究大气压氩气条件低载气流量下介质阻挡放电的放电特性,通过拍摄放电图像、光谱分析、测量放电波形图等手段研究了大气压氩气条件下介质阻挡放电（DBD）的放电特性。分别考察了电压、频率、气隙间距和载气流量等参数对DBD特性的影响。实验结果表明：提高外加电压幅值和频率可以显著增强放电功率。提高电压幅值会产生更多的高能电子,提高放电频率可以改变高能电子的分布,使得高能量电子数密度升高,低能量电子数密度下降。气隙间距的减小可以明显提高放电均匀性。载气流量增大时,放电强度下降,但放电均匀性会得到提高。
In order to learn the discharge characteristics of dielectric barrier discharge with low flow rate under atmosphere pressure with argon, by means of taking discharge photographs, performing spectral analysis, measuring discharge waveform, and so on, the DBD characteristics with low flow rate in argon at atmospheric pressure was investigated. The effects of discharge voltage, frequency, gas discharge gap, and air flow rate were also investigated. The results show that the rise of applied voltage and frequency can improve the discharge homogeneity. And it can get more energetic electrons when the applied voltage increases. With the increase of frequency, the distribution of energetic electrons will change, the density of electrons with higher energy will increase, and the density of electrons with lower energy will decrease. With the decrease of air gap, the discharge uniformity will increase. With the increase of air flow rate, the intensity of discharge weakens, whereas the uniformity of discharge increases.
