Abstract

Dielectric Barrier Discharges (DBD) plasma at atmospheric pressure (APP) are characterized by the presence of at least one dielectric layer between metal electrodes in discharge space. A numerical simulation using one dimentional fluid model is performed precisely at various discharge conditions in helium plasma to calculate electrical characteristics such gas voltage and discharge current. The presente model solves the continuity equations for charged species and the electron energy balance equation, coupled with Poisson's equation, by the finite element method; using COMSOL Multiphysics software. a parallel plate dielectric barrier discharge (DBD) scheme is considered and a peak-to- peak voltage of 1kV, a low frequency power source of 200 Hz, a disharge gap of 3 mm and a dielectric constant of 10 are applied as input parameters. Effect of applied voltage, driven frequency and secondary emission of electrons is studied. The obtained results are given in terms of temporal variations of descharge current.
