Numerical study of atmospheric pressure He plasma jets with dual-channel inlet under different electrode structures

  • 摘要: 采用二维轴对称流体模型对单电极结构(不锈钢针管)和双电极结构(不锈钢针管-高压环形电极)下同轴双通道进气的大气压氦气等离子体射流进行了对比研究。研究表明:相比于单电极结构,双电极结构下射流的传播速度明显降低,介质管内尤为严重。同时双电极结构下射流的空间结构也发生了显著变化。在单电极结构下,随射流发展由环形中空结构转变为实心圆盘结构;而在双电极结构下则呈现出实心圆盘结构至环形中空结构再至实心圆盘结构的演化过程,改善了射流空间分布的均匀性。此外,还研究了双电极结构下高压环形电极厚度对射流的影响。研究表明,随环形电极厚度的增加,射流的传播速度进一步降低,射流通道径向收缩,同时环形中空结构的射流内径减小,进而改善了射流径向分布的均匀性。
