Abstract
This study is a contribution to the modeling of plasma discharges. The numerical model proposed is particle type, applied to argon plasma generated by a continuous discharge.
A microscopic particle model is used for solving the Boltzmann equation by considering a finite number of particles to represent the charged species. The study of the electrical behavior of plasma is performed using a PIC (Particle-In-Cell) model whitch is well suited for low-pressure no-collision plasmas. This model provides the plasma characteristics (potential, charge densities). The principle of the PIC method is based on sampling (mesh) in a 1D of the space of the reactor between two flat and parallel electrodes in which particles move under the action of electric field (applied). This method makes it possible to determine the values of electric fields (steady state and time) at every point of contact for any interpolation from the numerical values obtained by the method of finite differences.
