| Résumé : |
Dielectric barrier discharges operating at atmospheric pressure are generally filamentary type discharges, but under particular conditions, they can be homogeneous. The present work consists, on the one hand, in developing a one-dimensional numerical fluid model to describe the physic properties (charge densities, electronic temperature, electric fields and electric potential) and the electrical characteristics (discharge current, gas voltage and Lissajous curve) of dielectric barrier (DBD) discharges at atmospheric pressure and ambient temperature. For this, we first developed a model using the commercial software COMSOL Multiphysics, in the case of volume discharges. The study is developed in the case of a volumic DBD powered by a sinusoidal signal, in the case of helium and argon plasmas, considering the effect of some parameters of the device. Subsequently, we developed a second model to describe the behavior of surface dielectric barrier discharges, in order to function as an actuator able of controlling the flow velocity of fluids. Air and helium are taken as a gaseous fluid for this numerical study. Furthermore, we have developed a device for the production of ozone by DBD; the experimental results concern the comparison of this production in the case of two different configurations of the device in the case of oxygen plasmas and carbon dioxide. |
