| Abstract: | Based on the hydrodynamic equations of plasma, a numerical model is proposed for describing the formation and transport of the streamer during positive pulse corona discharge and the general integral expression for the electric field due to the streamer space electric charges is derived. By means of the flux corrected transport (FCT) algorithm, solution with the numerical method is carried out for the model with respect to the ultra narrow pulsed voltage wave form used in the experiment, and the space time distribution of the parameters along the axis of the streamer propagation, such as the density of charged particles, electric field, and temperature of electron, has been obtained. |
