In this study, a dielectric barrier discharge (DBD) non-thermal plasma experimental set-up is utilized to investigate the effect of design parameters including the configuration and type of electrodes as well as the size of the reactor on the energy consumption and the rate of ozone generation. Results show that increasing the residence time by applying a larger length of the inner electrode causes an earlier plasma ignition, as well as formation of larger amounts of ozone for a given specific input energy (SIE). Changing the configuration and the type of the ground electrode shows that this electrode configuration is a dominant parameter for enhancing the energy yield in the plasma reactor. Furthermore, it was noted as the size of the reactor is increased, by increasing the gap between the electrodes, higher level of SIE is needed to reach the same level of ozone concentration.
