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…
An alternative simulation approach for surface flashover in vacuum using a 1D2V continuum and kinetic model
Guang-Yu Sun, Ru-Hui Lian, Shu Zhang +6
Surface flashover across insulator in vacuum is a destructive plasma discharge which undermines the behaviors of a range of applications in electrical engineering, particle physics…
A computational study on the energy efficiency of species production by single-pulse streamers in air
Baohong Guo, Jannis Teunissen
We study the energy efficiency of species production by streamer discharges with a single voltage pulse in atmospheric dry air, using a 2D axisymmetric fluid model. Sixty different…
Vlasov Simulation of Emissive Plasma Sheath with Energy-Dependent Secondary Emission Coefficient and Improved Modeling for Dielectric Charging Effects
Guang-Yu Sun, Shu Zhang, Bao-Hong Guo +2
A one dimensional Vlasov Poisson simulation code is employed to investigate the plasma sheath considering electron induced secondary electron emission (SEE) and backscattering. The…
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…
A computational study of steady and stagnating positive streamers in N2-O2 mixtures
Xiaoran Li, Baohong Guo, Anbang Sun +2
In this paper, we address two main topics: steady propagation fields for positive streamers in air and streamer deceleration in fields below the steady propagation field. We genera…
