Accelerating kinetic plasma simulations with machine learning generated initial conditions
Andrew T. Powis, Domenica Corona Rivera, Alexander Khrabry +1
Computer aided engineering of multi-time-scale plasma systems which exhibit a quasi-steady state solution are challenging due to the large number of time steps required to reach co…
Model of a transition from low to high ablation regime in a carbon arc
A. Khrabry, I. D. Kaganovich, A. Khodak +2
Graphite ablation in a presence of inert background gas is widely used in different methods for the synthesis of carbon nanotubes, including electric arc and laser/solar ablation.…
Validated two-dimensional modeling of short carbon arcs: anode and cathode spots
J. Chen, A. Khrabry, I. D. Kaganovich +3
In order to study properties of short carbon arcs, a self-consistent model was implemented into a CFD code ANSYS-CFX. The model treats transport of heat and electric current in the…
Validated Modeling of Atmospheric-Pressure Anodic Arc
Alexander Khrabry, Igor D. Kaganovich, Andrei Khodak +2
We performed self-consistent modeling of the atmospheric-pressure plasmas produced by arc discharges. Special numerical procedure for coupling of the plasma current, emission curre…
Synthesis of nanoparticles in carbon arc: measurements and modeling
Shurik Yatom, Alexander Khrabry, James Mitrani +5
This work studies the region of nanoparticle growth in atmospheric pressure carbon arc. Detection of the nanoparticles is realized via the planar laser induced incandescence (PLII)…
Effect of polarization forces on atom deposition on a non-spherical nanoparticle. Monte Carlo simulations
Valerian Nemchinsky, Alexander Khrabry
Trajectories of a polarizable species (atoms or molecules) in the vicinity of a negatively charged nanoparticle (at a floating potential) are considered. The atoms are pulled into…
