Abstract :
A 3-D streamer model that incorporates photoionization phenomena in atmospheric pressure air has been developed. It is applied to both point-plane and plane-plane electrode configurations in order to examine phenomena that have no cylindrical symmetry. The role of spontaneously distributed plasma spots in the propagation path of a streamer in discharge branching is then analyzed. Streamer advancement that ignites from a sharp point electrode is also presented in a full 3-D simulation. Images of the electron density evolution in the interelectrode space for the aforementioned configurations when the plasma spots interact with the streamer head are presented.
