1D model of Dielectric Barrier Discharges for Nitrogen N2 and Oxygen O2simulated by COMSOL Multiphysics
Résumé
The release of greenhouse gases into the atmosphere, which rose in concentration with the completion of industrial and the growing usage of fossil fuels, is the cause of global warming. Additionally, everyone is exposed to environmental pollution caused by exhaust gases; in certain professional settings, exposure levels are noticeably greater than those of the general public [1]. The treatment of air through innovative and energy-efficient processes remains a significant challenge for improving our living conditions, particularly in residential areas. A promising solution involves using electric discharge plasma [2]. Nitrogen oxides make up a large proportion of these pollutants, two nitrogen compounds that have a great effect on the environment are NO and NO2. they are easily generated in atmospheric plasma using N2 and O2 gases. In our research, we focus on the impact of nitrogen oxides on the environment and their removal methods [3]. In this work we have presented two model of DBD (Dielectric-Barrier Discharges) for nitrogen N2 and oxygen O2, simulated by COMSOL Multiphysics which is based on fluid model to observe the Spatiotemporal distribution of electrons and different species in the plasma.
