2D and 3D modeling of the appearance of streamers in strong fields Trajectories tracing of charged particles

This work represents a simulation and a representation of aspects of electric discharge type streamer formation, and then the trajectories lines of charged particles in 2D and 3D on a laboratory model subjected to a high voltage. Our study is to compare the parameters that are the potential V, the electric field,the lines of electric field, the trajectories lines of the particles, the number of charged particles, their velocity and their density, the inter-electrodes distance and the minimum and maximum distances of trigger of the electric discharge type streamer on studied model. The steps followed are the electrostatic study and the path tracing of the charged particles. This study, yielded results that have shown that thousands of field lines could be analyzed simultaneously with reasonable computing efforts, the representation in 2D and 3D of streamer and its parameters is possible and gives clear and very precise information, the reduction in the inter-electrodes distance is a parameter that favors the formation of electric discharges type streamer and it is possible to determine the minimum distance and maximum distance trigger on studied model.
