The Effect of Relative Humidity on Ozone Production by Corona Discharge in Oxygen or Air – A Numerical Simulation – Part II : Air

The simulation of the temporal evolution of the various neutral gaseous species studied (O, O3, H, OH, HO2, H2O2, N, NO, NO2, NO3, N2O, N2O5, HNO2, and HNO3) use corona effects. The physical conditions of the discharge were used. The reactions take place in dry or humid air, after the dissociation of O2, N2, and H2O by an electronic pulse. When water vapor is present, there is a probability of production of H2O2, HNO2, and HNO3 in air. Temperature and humidity have cumulative effects. With multiple pulses, the O3 maximal concentration is obtained for a limited number of pulses.
