ABSTRACT: Theoretical
investigation of nitrogen-silver arc transport properties and an arc plasma model
in stationary state have studied at low temperature i.e. between 3500 K and 13,000 K at atmospheric pressure. Results showed
that the presence of small amounts of metal vapours, which have low ionization potential
such as silver, modify the plasma characteristics. The solution of Elenbaas-Heller
gives us some information about the effect of metal vapours emitted from electrode
on the characteristics of the arc column. We concluded that a small fraction of
metal vapours in the arc column modify the electric field, current and the axial
temperature.
