NO-N2系统不同电离度下非平衡等离子体脱除NO的数值模拟
Numerical Simulation on the Removal of NO in NO-N2 Mixtures by Non-equilibrium Plasma With Different Ionization Degree
摘要
Abstract
The behavior of main particle species and the removal of NO with different ionization degrees were analyzed and calculated by using the simple model of removing NO in NO-N2 mixtures under non-equilibrium plasma discharge. The results show that the electron number density presents the exponential decay rule along with the time change; the initial electron relative number density is the critical factor to the removal of NO in non-equilibrium plasma, the removal efficiency of NO increases with the initial electron relative number density increases; As intermediate products, N and O have high number densities under higher ionization degrees, N and O number densities rise fast first and then decay fast to zero. The final reaction products are N：, as well as some O2 and a little NO2. O2 production increases with the ionization degree increases, the maximum of O2 is the same order of magnitude with the initial NO number density; the temporal changes of NO2 production with different ionization degrees are complex, NO2 production is quite low if the ionization degree is very high or very low, the maximum of NO2 is lower at least one order of magnitude than the initial NO number density.关键词
