摘要
针对微通道气液两相介质阻挡放电(DBD)固氮反应路径研究需求,提出一种基于发射光谱诊断DBD特征参数的方法.根据气液两相DBD固氮实验结果,进一步利用测得的发射光谱获取DBD等离子体有关特性参数和活性粒子成分等信息,深入分析DBD固氮反应路径.实验结果表明,该DBD发射光谱诊断方法可在DBD固氮反应过程中准确测定N2的振动温度和转动温度以及活性粒子成分,避免传统侵入式测量手段对DBD固氮反应的影响,为气液两相DBD固氮反应路径研究提供一种可靠实用的新手段.
Abstract
To study the nitrogen fixation reaction path in micro-channel gas-liquid two-phase dielectric barrier discharge(DBD),we propose a method to determine DBD characteristics using emission spectra.Based on the experimental results obtained for gas-liquid two-phase DBD nitrogen fixation,the characteristic parameters and active particle composition of DBD plasma are derived using the measured emission spectra,facilitating an in-depth analysis of the DBD nitrogen fixation reaction path.The experimental results indicate that the proposed method can accurately determine the vibration temperature,rotation temperature,and active particle composition of N2 during the DBD nitrogen fixation reaction.This approach circumvents the plausible effects of traditional intrusive measurement methods on the nitrogen fixation reaction of DBD.Therefore,this study offers a novel,reliable,and practical method for investigating the gas-liquid two-phase DBD nitrogen fixation reaction path.
