鉴于高气压下的沿面介质阻挡放电发生器在工业应用以及等离子体电磁屏蔽技术领域的重要应用前景,在梳状电极结构的沿面介质阻挡放电发生器基础上设计了两种电极结构的等离子体发生器,并通过边界元方法得到两种结构类型沿面放电发生器的静态场强分布。从计算结果来看,相比较于梳状电极结构的沿面放电发生器,改进后的放电发生器在空间的分布更有利于在高气压下产生较厚的等离子体层。实验结果表明:这两种结构形式的发生器放电效果明显优于梳状电极结构的发生器。
In view of the important application prospects of the creeping dielectric barrier discharge generator under high atmospheric pressure in industrial applications and plasma electromagnetic shielding technology, plasma generation of two electrode structures is designed on the basis of the creeping dielectric barrier discharge generator of the comb-shaped electrode structure The static field strength distributions of two types of structural creeping discharge generators are obtained by the boundary element method. From the calculation results, the distribution of the improved discharge generator in space is more favorable for generating a thicker plasma layer under high pressure than that of the creeping discharge generator having a comb-shaped electrode structure. The experimental results show that the discharge of these two kinds of structure generators is obviously better than that of comb-shaped electrode generator.
