| Abstract: | The numerical simulation for the removal of NO under pulse corona discharge using CHEMKIN4.1 cou-pled with FLUENT6.2 software was discussed.The reaction rate constant of the ionization of N2/O2 by electron-impact dissociation was calculated by the lumped kinetic model of pulse corona discharge,and a kinetic model in the system of NO/O2/N2 under pulse corona discharge was obtained.The kinetic mechanism was analyzed by the sensitiv-ity analysis method in CHEMKIN.The concentrations of free radicals(N,O)were pr... |
