Evolution of positive streamers in air over non-planar dielectrics: Experiments and simulations
Hans Kristian Meyer, Robert Marskar, Frank Mauseth
We study positive streamers in air propagating along polycarbonate dielectric plates with and without small-scale surface profiles. The streamer development was documented using li…

3D fluid modeling of positive streamer discharges in air with stochastic photoionization
Robert Marskar
Streamer discharges are thin plasma channels that precede lightning and sparks. They usually evolve in bundles as stochastic tree-like structures and are inherently difficult to mo…

Adaptive multiscale methods for 3D streamer discharges in air
Robert Marskar
We discuss spatially and temporally adaptive implicit-explicit (IMEX) methods for parallel simulations of three-dimensional fluid streamer discharges in atmospheric air. We examine…
