Previous and Current Research

  •  investigations of multi-component thermal plasma of electric arc discharges between evaporated electrodes (both metal and composite electrodes) in the different kinds of gases mixtures;
  •  investigations of peculiarities of thermal plasma-electrode’s surface interactions (both electrode’s surface behaviour and mass transfer in the electric arc discharge gap);
  •  optical (emission and absorption) spectroscopy techniques in plasma diagnostics;
  •  development of microprocessor systems in plasma source generation and arc discharge investigations;
  •  transport properties of multi-component plasma with metal vapours;
  •  underwater electric spark discharge.

Group leader: Anatolii Veklych, Dr. Sci. (Phys.&Math.), Prof.

Special hardware and software complex tools were developed to investigate the physical properties of thermal multicomponent plasma of electric arc discharge in metal vapours by optical spectroscopy. It was found, that the thermal dissociation causes the deviation of local thermodynamic equilibrium in plasma of electric arc between the melting copper electrodes in various molecular gases (air or carbon dioxide). This threshold phenomenon is determined by the ratio of the inputted into discharge energy and dissociation energy of molecular gas. To describe a chemically non-equilibrium thermal plasma of molecular gas the two-temperature model is developed. It is shown that a plasma thermal conductivity of discharge in molecular gases, in contrast to the electrical conductivity, does not depend on a presence of copper impurities in plasma in the temperature range 5000 – 9000 K. This conductivity is determined by its reaction component, which is caused by dissociation of molecules. The relation of plasma parameters of arc discharge in air between composite electrodes and à presence of secondary structure on the surface of electrodes is found. For the first time the radial distribution of copper atom concentrations in plasma was measured in a discharge gap with a presence of a drop. The influence of Cu I spectral lines’ reabsorption in the radiation of multicomponent thermal plasma with copper impurities is studied. It is proposed to use the thermal plasma of electric arc between multicomponent electrodes as plasma source for the spectral lines and spectroscopic data selection.
