SINOPSIS

The boundary problem describing the generation of dielectric barrier discharge in air near a surface of dielectric plate by means of spatial periodic system of exposed electrodes with applied external harmonic voltage is formulated in the framework of a two-dimensional statement. Demonstrated is the significance of taking into consideration such parameters as the finite thickness of the exposed electrodes, an existence of the Knudsen layer near the plate surface and the electrodes, the finite rates of desorption and recombination of charged particles on a dielectric surface, the strength of the electric field induced by superficial charge on a dielectric fat the calculation of the conduction current, the volumetric force acting on a gas from the discharge, and the heat release (Joule dissipation) in the discharge. Numerical investigation of an influence of some physical parameters on mentioned characteristics of barrier discharge is carried out.
