Abstract

We present in this paper a numerical description of an atmospheric pressure dielectric barrier discharge in helium. The presented model is based on the fluid description, which is commonly used for such high pressure discharges. In our research we study the influence of the plasma operating parameters such as voltage amplitude and frequency, the thickness and nature of the dielectric and also the influence of the impurities present in the discharge gas. We present electrical current profiles for typical discharge conditions to assess the validity of the model. The electrical profiles show a good agreement with the experimental results, although there still are quantitative differences.
