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…
