Implicit and Coupled Multi-Fluid Solver for Collisional Low-Temperature Plasma
Robert Arslanbekov, Vladimir Kolobov
We present a new multi-fluid, multi-temperature plasma solver with adaptive Cartesian mesh (ACM) based on a full-Newton (non-linear, implicit) scheme for collisional low-temperatur…
Plasma Stratification in Radio-Frequency Discharges of Noble Gases
Vladimir I Kolobov, Robert R Arslanbekov, Dmitry Levko +1
We conducted experimental studies and computer simulations of standing striations in capacitive coupled plasma in Argon gas. Standing striations were observed at frequencies 3.6, 8…
On the expansion of non-ideal copper plasma into vacuum
Dmitry Levko, Robert R. Arslanbekov, Vladimir I. Kolobov
The expansion of non-ideal copper plasma into vacuum is analyzed for the conditions typical to explosive electron emission in vacuum arcs. The gas-dynamic model solves the Euler eq…
Electron Groups in Solar Wind and Gas Discharge Plasmas
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
The formation of electron groups is a common phenomenon in gas discharges and space plasmas. We describe similarities between electron kinetics in solar wind, cathode region of glo…
Boltzmann-Fokker-Planck Kinetic Solver with Adaptive Mesh in Phase Space
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
We describe the implementation of kinetic solvers in 1d2v phase space using adaptive Cartesian mesh. Spherical coordinates in velocity space are used to simplify the Lorentz and Fo…
Kinetic Solvers with Adaptive Mesh in Phase Space for Low-Temperature Plasmas
Vladimir Kolobov, Robert Arslanbekov, Dmitry Levko
We describe the implementation of 1d1v and 1d2v Vlasov and Fokker-Planck kinetic solvers with adaptive mesh refinement in phase space (AMPS) and coupling these kinetic solvers to P…
