Streamers, sprites, leaders, lightning: from micro- to macroscales
Ute Ebert, Davis D. Sentman
"Streamers, sprites, leaders, lightning: from micro- to macroscales" was the theme of a workshop in October 2007 in Leiden, The Netherlands; it brought researchers from plasma phys…
Experiments on propagating and branching positive streamers in air
T. M. P. Briels, E. M. van Veldhuizen, Ute Ebert
This proceedings paper from 2004 contains figures of discharges in different gap lengths at the same potential that are not available elsewhere. The 2004 abstract: The evolution of…
Moving boundary approximation for curved streamer ionization fronts: Solvability analysis
Fabian Brau, Benny Davidovitch, Ute Ebert
The minimal density model for negative streamer ionization fronts is investigated. An earlier moving boundary approximation for this model consisted of a "kinetic undercooling" typ…
Positive and negative streamers in ambient air: modeling evolution and velocities
Alejandro Luque, Valeria Ratushnaya, Ute Ebert
We simulate short positive and negative streamers in air at standard temperature and pressure. They evolve in homogeneous electric fields or emerge from needle electrodes with volt…
Interaction of streamers in air and other oxygen-nitrogen mixtures
A. Luque, U. Ebert, W. Hundsdorfer
The interaction of streamers in nitrogen-oxygen mixtures such as air is studied. First, an efficient method for fully three-dimensional streamer simulations in multiprocessor machi…
Saffman-Taylor streamers: mutual finger interaction in an electric breakdown
Alejandro Luque, Fabian Brau, Ute Ebert
Bunches of streamers form the early stages of sparks and lightning but theory presently concentrates on single streamers or on coarse approximations of whole breakdown trees. Here…
