Résumé

This work is devoted to the determination of corona ignition threshold for non-thermal plasma generation and to the optimization of various kinds of plasma reactor geometries for exhaust gas treatment applications. The tested plasma reactor geometries were cylindrical. Some reactors have dielectric barrier made of glass or quartz in order to observe the discharges. First, the distributions of electric field and energy in reactors have been simulated. Then, current and voltage waveforms have been measured to check the discharge appearance. Geometrical singularities have been detected by both luminescence and current measurements to avoid unwanted current distortions. The experimental analyze shows the evolution of resistive and reactive components of current associated to corona discharges when increasing the voltage.
