Generation of surface DBD on rough dielectric: Electrical properties, discharge-induced electric wind and generated chemical species

This paper deals with the effects of the rugosity due to glass beads on the characteristics of a surface DBD. To achieve this, an electromechanical investigation has been conducted. The results show that the glass beads do not alter the power consumption. While, the velocity of the electric wind is reduced about 1 m/s for discharges with an important surface roughness. Then, the rate of chemical species has been recorded. These measurements show that the production of chemical species is not correlated with the induced electric wind by the plasma, but is rather due to the increase in exchange surface.
