A 3D kinetic Monte Carlo study of streamer discharges in CO

Robert Marskar

We theoretically study the inception and propagation of positive and negative streamers in CO. Our study is done in 3D, using a newly formulated kinetic Monte Carlo discharge m…

Genesis of column sprites: Formation mechanisms and optical structures

Robert Marskar

Sprite discharges are electrical discharges that initiate from the lower ionosphere during intense lightning storms, manifesting themselves optically as flashes of light that last…

Stochastic and self-consistent 3D modeling of streamer discharge trees with Kinetic Monte Carlo

Robert Marskar

This paper contains the foundation for a new Particle-In-Cell model for gas discharges, based on Ito diffusion and Kinetic Monte Carlo (KMC). In the new model the electrons are des…

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…

An adaptive Cartesian embedded boundary approach for fluid simulations of two- and three-dimensional low temperature plasma filaments in complex geometries

Robert Marskar

We review a scalable two- and three-dimensional computer code for low-temperature plasma simulations in multi-material complex geometries. Our approach is based on embedded boundar…
