Abstract

Summary form only given. A numerical study of a negative corona discharge in air at atmospheric pressure in a non-uniform electric field: a cylindrical arrangement with earthed inner electrodes is presented. Results were obtained by solving numerically Poisson´s equation coupled with the continuity equations for electrons, positive, and negative ions, and considering the space-time evolution, as well as the electric field distribution and the current behaviour. The effects of ionization, attachment, recombination, electron diffusion are included. Calculations were made using a two dimensional axisymmetric numerical model. The calculated values were compared with the experimental results
