3D particle-in-cell simulations of negative and positive streamers in C4F7N-CO2 mixtures
Baohong Guo, Ute Ebert, Jannis Teunissen
We investigate negative and positive streamers in C4F7N-CO2 mixtures through simulations. These mixtures are considered to be more environmentally friendly than the insulating gas…
3D modeling of positive streamers in air with inhomogeneous density
Baohong Guo, Ute Ebert, Jannis Teunissen
We study the effect of an inhomogeneous gas density on positive streamer discharges in air using a 3D fluid model with stochastic photoionization, generalizing earlier work with a…
Estimating the properties of single positive air streamers from measurable parameters
Dennis Bouwman, Hani Francisco, Ute Ebert
We develop an axial model for single steadily propagating positive streamers in air. It uses observable parameters to estimate quantities that are difficult to measure. More specif…
Quantitative modeling of streamer discharge branching in air
Zhen Wang, Siebe Dijcks, Yihao Guo +5
Streamer discharges are the primary mode of electric breakdown of air in lightning and high voltage technology. Streamer channels branch many times, which determines the developing…
3D particle simulations of positive air-methane streamers for combustion
Dennis Bouwman, Jannis Teunissen, Ute Ebert
Streamer discharges can be used as a primary source of reactive species for plasma-assisted combustion. In this research we investigate positive streamers in a stoichiometric air-m…
A computational study of accelerating, steady and fading negative streamers in ambient air
Baohong Guo, Xiaoran Li, Ute Ebert +1
We study negative streamers in ambient air using a 2D axisymmetric fluid model. Depending on the background electric field, we observe accelerating, steady and fading negative stre…
