Rarefied xenon flow in orificed hollow cathodes
Pierre-Yves C. R. Taunay, Willca Villafana, Sangeeta P. Vinoth +2
A parametric study is conducted to quantify the effect of the keeper electrode geometry on the neutral flow quantities within orificed hollow cathodes, prior to cathode ignition. T…
Numerical benchmark of transient pressure-driven metallic melt flows
L. Vignitchouk, A. Khodak, S. Ratynskaia +1
Fluid dynamics simulations of melting and crater formation at the surface of a copper cathode exposed to high plasma heat fluxes and pressure gradients are presented. The predicted…
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)…
Investigation of the Short Argon Arc with Hot Anode, Part II: Analytical Model
A Khrabry, I. D. Kaganovich, V. Nemchinsky +1
Short atmospheric pressure argon arc is studied numerically and analytically. In a short arc with inter-electrode gap of several millimeters non-equilibrium effects in plasma play…
