中文摘要：
为了获得氩气/空气等离子体助燃激励器的特性,首先在空气中加入少量氩气的条件下,对条状、王状和网状三种不同电极形状的等离子体助燃激励器的放电特性进行对比,实验结果表明电极形状对激励器放电特性影响不大。然后对条形电极在纯空气和10%氩气/90%空气两种条件下的放电特性和发射光谱进行研究,发现加入氩气后,放电参数变化趋势与纯空气相似,但电流脉冲增多,放电均匀度增加,起始放电电压由27kV降低到24kV,并且介质阻挡放电发射光谱增强。
英文摘要：
In order to obtain the characteristics of argon/air plasma assistant combustion actuators,experiments of three different actuators with normal,paratactic and meshy electrode configurations were respectively performed in argon/air mixture firstly,the results showed that the shape of electrode has little influence on the discharge characteristics.Then normal electrode was applied to study spectrum and discharge characteristics under the condition of 100% air and 10% argon/90% air.The comparison showed that,though in mixture the law of discharge characteristic was the same as that of pure air,discharge current and emission spectrum were strengthened,and initial discharge voltage reduced from 27 to 24 kV.
