In this review we describe a transient type of gas discharge which is commonly called a
streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers …

Guided ionization waves, or plasma streamers, are increasingly important for many
applications in spanning materials processing and biomedicine. The highly reproducible …

Recent development in lightning discharges including transient luminous events (TLEs) and
global electric circuit are discussed. Role of solar activity, convective available potential …

We present and compare six simulation codes for positive streamer discharges from six
different research groups. Four groups use a fully self-implemented code and two make use …

We present an open-source plasma fluid code for 2D, cylindrical and 3D simulations of
streamer discharges. The code is based on the Afivo framework, which features adaptive …

We investigate how photoionization, electron avalanches and space charge affect the
inception of nanosecond pulsed discharges. Simulations are performed with a 3D PIC-MCC …

We use numerical simulations to study the dynamics of surface discharges, which are
common in high-voltage engineering. We simulate positive streamer discharges that …

Positive streamers need a source of free electrons ahead of them to propagate. A streamer
can supply these electrons by itself through photo-ionization, or the electrons can be present …

Afivo is a framework for simulations with adaptive mesh refinement (AMR) on quadtree (2D)
and octree (3D) grids. The framework comes with a geometric multigrid solver, shared …

We introduce the generic structure of a growth model for branched discharge trees that
consistently combines a finite channel conductivity with the physical law of charge …
