摘要
为了研究激发粒子的演化规律,优化等离子体助燃参数,在不同的电极形状、电极间隙、气体流量、放电电压条件下,对介质阻挡放电的发射光谱进行了实验测量与分析。研究发现:网形电极结构的激励器光谱最强,王形次之,条形最低;随着电极距离的增大,发射光谱强度呈现先慢后快的下降趋势;工作介质流量有一个最佳值,为60 g/s;随着驱动电压或频率的增加,微放电通道增多,放电增强,发射谱线强度增强。
In order to study the evolution laws of the excited particles in air plasma and optimize the combustion-supporting parameters,this paper has carried on an experimental measuring and analysis on DBD emission spectrum with actuators electrodes of different shapes,electrode gaps,gas flow, discharge conditions,voltage and frequency.The experiment results show that spectrum of meshy electrode configurations is the most intensive,the next and the lowest are stripline and paratactic electrode shape;emission spectral intensity decrease while the electrode distance increase;and the curve is a simile semi-parabolic,the optimum gas flow is 60 gram per second;once the applied voltage or frequency increase,micro-discharge channels will increase, emission spectral line intensity will strengthen.
