Abstract

In this work, we studied the gas temperature due to joule heating effect in N<sub>2</sub>/O<sub>2</sub> dielectrics barriers discharge (DBD). The numerical investigation is carried using a one-dimensional fluid model, in which the continuity equations of electron and ion and Poisson's equation are considered. The study of gas heating development in nitrogen-oxygen plasma discharge was performed by using heating transport equation. The systems of equations were solved along the gap distance of the DBD with the aim to determine the gas temperature profiles. The obtained results show that gas heating becomes important in the cases when the secondary electron emission coefficient takes large values, and with high values of nitrogen in the mixture.
