NUMERICAL STUDY OF GAS HEATING IN OZONE GENERATED BY DBD IN OXYGEN

摘要

The goal of the present work is to highlight the gas temperature effect in ozone generated by dielectric barrier discharge (DBD) in pure oxygen (O_2). In this study, a one-dimensional fluid model was used to describe the discharge behavior. The study of the gas heating phenomena study in the frame of this paper is due to the gas heating effect. The gas temperature profile obtained in the DBD in oxygen was calculated by means of the heat transport equation. The results show that the rise of the gas temperature in the DBD inoxygen is more important near the dielectrics. The high value of gas temperature in this region is limited by the increase in the electric field and ion current density.
