Abstract
Ozone production by corona discharge in air is analysed as a function of current pointing out the characteristic current ranges with relation to the discharge regimes. Taking into account the temporal evolution of the discharge, microscopic parameters are analysed for each range and correlated with the elementary processes of ozone formation. The study allows an interpretation of experimental results for ozone production in the various discharge regimes. The conclusions may also be used as starting points for designing more efficient reactors.
