Abstract


Theoretical investigation of nitrogen-copper arc transport properties and an arc plasma model in stationary state have studied at low temperature i.e. between 3,500K and 13,000K at atmospheric pressure.  Results showed that the presence of small amounts of metal vapours, which have low ionization potential such as copper, 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.
