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…
Reconnection and merging of positive streamers in air
S. Nijdam, C. G. C. Geurts, E. M. van Veldhuizen +1
Pictures show that streamer or sprite discharge channels emerging from the same electrode sometimes seem to reconnect or merge though their heads carry electric charge of the same…
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…
Impulse Formulations of Hall Magnetohydrodynamic Equations
Bhimsen K. Shivamoggi
Impulse formulations of Hall magnetohydrodynamic (MHD) equations are developed. The Lagrange invariance of a generalized ion magnetic helicity is established for Hall MHD. The phys…
Positive and negative streamers in ambient air: measuring diameter, velocity and dissipated energy
T. M. P. Briels, J. Kos, G. J. J. Winands +2
Positive and negative streamers are studied in ambient air at 1 bar; they emerge from a needle electrode placed 40 mm above a planar electrode. The amplitudes of the applied voltag…
Positive streamers in air and nitrogen of varying density: experiments on similarity laws
T. M. P. Briels, E. M. van Veldhuizen, Ute Ebert
Positive streamers in ambient air at pressures from 0.013 to 1 bar are investigated experimentally. The voltage applied to the anode needle ranges from 5 to 45 kV, the discharge ga…
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…
Multiple X-ray bursts from long discharges in air
C. V. Nguyen, A. P. J. van Deursen, U. Ebert
A lightning surge generator generates a high voltage surge with 1.2 microsec. rise time. The generator fed a spark gap of two pointed electrodes at 0.7 to 1.2 m distances. Gap brea…
Stereo-photography of point-plane streamers in air
S. Nijdam, J. S. Moerman, T. M. P. Briels +2
Standard photographs of streamer discharges show a two-dimensional projection. We here present stereo-photographic images that resolve their three-dimensional structure. We describ…
Positive streamers in ambient air and a N2:O2-mixture (99.8 : 0.2)
T. M. P. Briels, E. M. van Veldhuizen, Ute Ebert
Photographs show distinct differences between positive streamers in air or in a nitrogen-oxygen mixture (0.2% O2). The streamers in the mixture branch more frequently, but the bran…
