Numerical modeling of negative-corona discharge in oxygen under different pressures
چکیده انگلیسی

This paper presents a numerical model of the negative-corona discharge in oxygen under different pressures at room temperature. The model assumes the presence of two charged species: electrons and O2- ions. The boundary element and finite-element methods have been used to calculate the electric field and the method of characteristics has been employed for the densities of electrons and O2- ions. The simulation has been performed for an axisymmetrical point-plane geometry with a hyperboloidal needle perpendicular to infinitely large conducting plate. The results of computations show the effect of pressure on the electron and negative-ion densities along the axial direction, electric field distribution along the axis of symmetry and current density on the ground plane.
