Abstract
Summary form only given, as follows. The development of a pulsed corona discharge plasma is investigated theoretically using a self-consistent two-dimensional numerical model in this paper. The motions of charged species under the action of space-charge electric field are determined by solving the continuity equations of electrons, positive ions and negative ions using a flux-corrected transport scheme. The electric field is obtained from the solution of Poisson's equation by a finite element method. The results of two-dimensional simulations in air at atmosphere pressure, are presented. The spatio-temporal electric field, electron density, positive ion density, negative ion density, net charge density and the velocity profile of an ionizing front are calculated, which explain well the physical characteristics of a pulsed corona discharge in air at atmosphere pressure.
