在介质阻挡放电等离子体N2/O2/H2O/HCHO体系中通过解Boltzmann方程,得到电子能量分布函数,利用得到的电子能量分布函数计算电子-分子碰撞反应速率常数.然后把有关的反应速率常数带入速率方程,计算得到该体系在介质阻挡放电时,·OH、HO2·和电子的浓度随时间的演变以及·OH、HO2·浓度随H2O、O2摩尔分数的变化,并将模拟结果与实验值进行了对比,两者符合得较好.
The electron energy distribution function is obtained by solving the Boltzmann equation in the dielectric barrier discharge plasma N2 / O2 / H2O / HCHO system, and the electron-molecule collision reaction rate constant is calculated by using the obtained electron energy distribution function. Then the related reaction rate constant band Into the rate equation, the evolution of the concentration of · OH, HO2 · and electrons over time and the change of · OH, HO2 · concentration with the molar fractions of H2O and O2 at dielectric barrier discharge were calculated. The simulation results were compared with the experimental values The comparison between the two is in good agreement.
