Abstract :
Assuming a constant molecular oxygen (O2) flow velocity, the expressions describing the dynamics of ozone generation in a silent discharge, for gas pressures higher than 100 torr, are obtained. Expressions for both atomic oxygen (O) and ozone (O3) are obtained applying a perturbative method and reduced to a compact form through the use of Green´s functions. The latter are of great aid for studying the generation of ozone for pulsed and continuous operation regimes depending explicitly on initial and boundary conditions. It is shown that the behavior of O and O3 densities is strongly dependent on time. Results reported here confirm the fact that, close to the electrodes, further production of high-concentration ozone can be obtained taking into account the time evolution
