Název v původním jazyce

Departure from thermodynamic equilibrium in thermal plasma arcjet, emission spectroscopy study

Popis výsledku v původním jazyce

This contribution deals with several aspects of equilibrium and non-equilibrium behavior in plasmas generated in water-argon plasma torch. We study these plasmas in controlled atmosphere with pressures between 500 Pa and 100 kPa. Emission spectroscopy and high-speed camera diagnostics are used. The study includes analysis of large number of emission spectral lines. From the hydrogen lines we are able to obtain electron density distribution in the plasma. This brings first insight into the non-equilibrium phenomena, by means of application of Griem’s or McWhirter’s criteria. We also analyze other lines of atomic and singly ionized argon and oxygen and in addition emission spectra of OH radical are measured. Using all these lines, Boltzmann plots are constructed and further details regarding departures from LTE are obtained. The relation between these data and supersonic flow phenomena is included.
