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…
Adaptive Kinetic-Fluid Models for Expanding Plasmas
Robert R. Arslanbekov, Vladimir I. Kolobov
We describe gas dynamic and plasma effects for transient plasma jets under different conditions. Our Unified Flow Solver (UFS) is evaluated for simulations of mixed continuum-raref…
Electrostatic PIC with adaptive Cartesian mesh
Vladimir I Kolobov, Robert R Arslanbekov
We describe an initial implementation of an electrostatic Particle-in-Cell (ES-PIC) module with adaptive Cartesian mesh in our Unified Flow Solver framework. Challenges of PIC meth…
A Discontinuous Galerkin Time-Domain Method with Dynamically Adaptive Cartesian Meshes for Computational Electromagnetics
Su Yan, Chao-Ping Lin, Robert R. Arslanbekov +2
A discontinuous Galerkin time-domain (DGTD) method based on dynamically adaptive Cartesian meshes (ACM) is developed for a full-wave analysis of electromagnetic fields in dispersiv…
Adaptive Kinetic-Fluid Solvers for Heterogeneous Computing Architectures
Sergey Zabelok, Robert Arslanbekov, Vladimir Kolobov
We show feasibility and benefits of porting an adaptive multi-scale kinetic-fluid code to CPU-GPU systems. Challenges are due to the irregular data access for adaptive Cartesian me…
Kinetic Solvers with Adaptive Mesh in Phase Space
Robert R. Arslanbekov, Vladimir I. Kolobov, Anna A. Frolova
An Adaptive Mesh in Phase Space (AMPS) methodology has been developed for solving multi-dimensional kinetic equations by the discrete velocity method. A Cartesian mesh for both con…
