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…
Nanoparticles growth in dynamic plasma
V. Vekselman, M. N. Shneider, Y. Raitses
Coagulation growth kinetics of nanoparticles in plasma is affected by inter-particle electrostatic forces due to charging phenomenon. In stationary plasmas, unipolar charging of pa…
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)…
Complex structure of the carbon arc discharge for synthesis of nanotubes
V. Vekselman, M. Feurer, T. Huang +2
Comprehensive non-invasive spectroscopic techniques and electrical measurements of the carbon arc revealed two distinguishable plasma synthesis regions in the radial direction norm…
Numerical simulations of runaway electron generation in pressurized gases
D. Levko, S. Yatom, V. Vekselman +3
The results of a numerical simulation of the generation of runaway electrons in pressurized nitrogen and helium gases are presented. It was shown that runaway electrons generation…
