Résumé

Ozone is widely known to be an important oxidizing agent that is used in many industrial processes, such as disinfecting water and air, due to the increasing concern for environmental protection. Composed of three oxygen atoms, it is a highly reactive and unstable gas in contrast to oxygen. Ozone may be created using a dielectric barrier discharge (DBD) generator. In order to improve conditions for effective ozone synthesis, a computational study of DBD's ozone creation in an O₂ offers important insights into the plasma chemistry involved. Such research contributes to the development of sustainable technologies for pollution control and environmental management. For oxygen plasma at atmospheric pressure, a one-dimensional (1D) model of a homogeneous DBD has been created in order to examine the spatiotemporal distribution of electrons and other species in the plasma. This model uses the finite element method to solve the electron energy balance equation in combination with Poisson's equation and the continuity equations for charged species using COMSOL Multiphysics software. The simulation's dielectric barrier discharge plasma was generated with a peak-to-peak voltage of 7 kV, a discharge gap of 1 mm, and a low frequency of 3 kHz. This study displays the courant, voltage, and density of both newly formed and pre-existing species.
