A
physical transient model and system of equations with
spherical symmetry, was formulated to describe the
interaction between metallic plasma ions with neutral gas, in
the outer region of a multicathode spot vacuum arc operated
with a background gas. The model considers the self-consistent
processes for typical values of arc parameters, including the
electron and ion drift velocities, the electron and neutral gas
temperatures, and the electrostatic potential profiles are obtained
from the border of the arc channel up to the discharge chamber
wall. It is studied that values of arc parameters strongly influences
the metallic plasma density and plasma potential distributions.
Biography
D F Devia did his under graduation form university National University of
Colombia-Manizales in implementation and automation of technical variables
of an industrial reactor used in the production of coatings by pulsed arc. He
has completed his masters in model of an AC / DC three - phase converted
for analysis of harmonic distortion. He received his PhD in kinetic modelling of
plasmas produced in cathode arcs in vacuum for applications in the processing
of materials from National University of Colombia.
