Study of ozone generation in an atmospheric dielectric barrier discharge reactor

•Ozone is generated using an atmospheric DBD reactor driven by a pulse power supply.•We model ozone generation efficiency with O2 concentration and energy density.•We compare the simulation results with references using different generation methods.•The simulation results agree surprisingly well with the references.

Ozone (O3) generation in a dielectric barrier discharge (DBD) reactor driven by a pulsed power supply was investigated at atmospheric pressure and room temperature. An O3 generation efficiency model is established in which discharge power, O2 concentration, gas flow rate, and volume of the discharge space are included. Constants in the O3 generation efficiency model were obtained by fitting the model with experiment results. O3 concentration can be simply calculated from the energy density and initial O2 concentration. Comparison on O3 concentrations from calculation with references is given.
