3D hybrid computations for streamer discharges and production of run-away electrons
Chao Li, Ute Ebert, Willem Hundsdorfer
We introduce a 3D hybrid model for streamer discharges that follows the dynamics of single electrons in the region with strong field enhancement at the streamer tip while approxima…
Moving boundary approximation for curved streamer ionization fronts: Numerical tests
Fabian Brau, Alejandro Luque, Benny Davidovitch +1
Recently a moving boundary approximation for the minimal model for negative streamer ionization fronts was extended with effects due to front curvature; this was done through a sys…
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…
