“…Numerous studies have been performed on strip electrode SDBD for SDBD applications. Our group demonstrated that annular SDBD can generate vertical flow fields and have a high airflow altitude [ 24 ], indicating good application prospects in aircraft anti-icing [ 25 ]. Therefore, based on our previous research results on the discharge characteristics of SDBD actuators [ 2 , 3 , 25 , 26 ], this study focused on the discharge characteristics of annular SDBD under water-covered conditions.…”

Surface dielectric barrier discharge (SDBD) has wide applications in flow control, wastewater treatment, and biomedicine. The dielectric surface of an SDBD actuator is generally attached to the water droplets during applications. Thus far, only a few studies have been conducted on the effects of water covering the dielectric surface on the discharge characteristics of SDBD. Therefore, the effects of water droplets on the discharge of an SDBD actuator based on a repetitive microsecond pulse power supply were investigated in this study. The results show that a filament micro-discharge channel forms between the light and dark regions at the internal edge of the SDBD high-voltage electrode and develops toward the center of the dielectric surface in the region without water droplet coverage. SDBD in the water-covered region was divided into two stages. This paper compares the electrical characteristics of SDBD with and without water droplet, and explores the electric field distortion effect of water droplet endpoints through 3D simulation.Based on the theories of water droplet polarization and gas discharge, the effects of water droplets on plasma development and surface charge accumulation under water-covered condition were analyzed. The water droplet plays a similar role as a "secondary electrode" during the discharge process.
