Abstract
A mathematical model was developed to describe the behavior of species in NO/N2 pulse discharge system, and to compute the concentration of the species by considering a series of chemical reactions into stiff ordinary differential equations. The evolution of various species changed with the residence time was studied respectively in two conditions: considering or non-considering the N(2D) and N2(A3Σu+) involved in the chemical reactions. The results showed that the evolution of N2O was more in line with the actual when considered the reactions involved N(2D) and N2(A3Σu+). When gas residence time reached 2.5 s, NO and NO2 could be totally removed, the concentration of NOx (N2O and N2O5) approximated 5×10-6. From 2.5 s to 3 s, a small amount of N2O and N2O5 was remaining and their concentrations were almost balanced when the residence time came to 3 s. At this time, the concentration of NOx approximated to 3.2×10-6.
