Influence of Electrode Gap on Characteristics of Dielectric Barrier Discharge

  • 摘要: 为研究不同电极间隙下的表面介质阻挡放电特性,利用相机拍摄等离子实物图,分析电极间隙对等离子延伸的影响;测量其放电波形,分析消耗功率随电极间隙的变化趋势;通过红外热像仪拍摄介质板表面温度分布,探究温度分布特性随间隙的变化,同时测量不同间隙下诱导气流速度大小,分析电极间隙对诱导气流的影响;利用电子天平分析电极间隙对表面介质阻挡放电(SDBD)装置体积力的影响;最后,分别对不同间隙下4个放电参数变化趋势机理进行了讨论. 研究结果表明:等离子体延伸度、消耗功率、最高温度、诱导气流速度以及体积力均随电极间隙的增加呈先增后减的变化趋势;在固定激励电压下,存在一个最佳放电电极间隙. 该研究结果为表面介质阻挡放电装置实现更好的流动控制提供了一定的参考.
