【 摘 要 】

Numerical simulation of sinusoidal Surface Dielectric Barrier Discharge (SDBD) is carried out. The configuration and parameters of the discharge are those considered experimentally in paper [1]. In this paper, dielectric disc was surrounded by high-voltage metallic electrode. 34 kHz 5.5 kV applied to HV electrode at atmospheric pressure. The objective of the current paper is to study mechanisms inducing flow motion over the disc. Numerical simulations are made with the two-dimensional model developed earlier in paper [2]. The model incorporates the transport of charged particles, Poisson equation for the electric field strength, and Navier-Stokes equations for the fluid. In addition to the bulk processes (mainly, ionization, recombination, drift and diffusion) the deposition of the charge on the dielectric surface is considered.
