PHYSICA SCRIPTA, ISSN: 0031-8949, DOI: 10.1088/0031-8949/2014/T161/014072, Vol.T161, pp.014072-1-4, 2014 Abstract:
Nitrogen and argon plasmas with a small admixture of air produced in a segmented plasmatron are studied both experimentally and theoretically. A two-temperature hydrodynamic model is used to simulate the plasma flow inside the plasmatron. The calculated plasma temperature and electron density are in reasonable agreement with the experimental values obtained from emission spectroscopy. The electron temperatures are several thousand kelvins higher than the atom temperatures, showing that the plasmas produced in the segmented plasmatron are in non-equilibrium. Keywords:
segmented plasmatron, plasma expansion, emission spectroscopy Affiliations:
