大气压氩气针-板介质阻挡放电的光电诊断OA北大核心CSCDCSTPCD

Electrical and Optical Diagnostics of Plasma Jet Generated by Needle-plate Dielectric Barrier Discharge at Atmospheric Argon

中文摘要英文摘要

利用针-板介质阻挡放电装置,在4 mm长的气隙中产生了大气压氩气射流等离子体。利用电学方法实现了对放电电流和电荷量的同时测量,并且对放电脉冲数和放电功率进行了研究;利用发射光谱法对放电等离子体进行了空间分辨测量,并根据ArⅠ696.54 nm的Stark展宽计算了等离子体的电子密度。结果发现:随着外加电压的增加,每个周期内的放电脉冲数增加,放电功率也增加。随着针头距离的增加,电子密度由2.94×1015 cm-3逐渐减小到2.28×1015 cm…查看全部>>

An atmospheric argon plasma jet was obtained with a needle-plate dielectric barrier dis-charge system. The discharge gap was kept at 4 mm and the argon gas flow rate was 0. 5 L/min. A test capacitor and a test resistance were connected in series in the circuit, and the discharge current and the transport charge were measured simultaneously. The average discharge power in a period of the applied voltage was calculated by Lissajous figure. The plasma jet was i…查看全部>>
