How thermal are (certain) thermal plasmas?
ICOPS 2000. IEEE Conference Record - Abstracts. 27th IEEE International Conference on Plasma Science (Cat. No.00CH37087), 2002Summary form only given, as follows. In a recent study Gao et al. (1999) have examined the assumption of a Maxwellian electron distribution function for an inductively coupled argon plasma at atmospheric pressure. By solving the Boltzmann equation the authors demonstrate that in fact deviations from a Maxwellian distribution can be detected.

Thermal plasmas for nanofabrication
Journal of Physics D: Applied Physics, 2011In this paper, we review the recent progress in nanofabrication by thermal plasmas, and attempt to define some of the most important issues in the field. For synthesis of nanoparticles, the experimental studies in the past five years are briefly introduced; the theoretical and numerical modelling works of the past 20 years are reviewed with some ...

Plasma chemistry and environmental protection: Application of thermal and non-thermal plasmas
Czechoslovak Journal of Physics, 1995The paper presents extensive opportunities for the use of thermal and non-thermal plasmas in chemical processes related to environmental protection. It describes particular homo- and heterogeneous reactions, resulting in decomposition of hazardous compounds. Examples refer to the processes at laboratory and on the industrial scale.

Plasma-neutral interaction in thermally collapsed plasma
Journal of Nuclear Materials, 1997A systematic experimental study of the power, length, and gas pressure dependence of plasma density and temperature profiles in thermally collapsed magnetized helium plasmas has been performed on the Princeton divertor simulator apparatus. The recombination edge and recombination radiation from highly excited levels (to n = 12) have been identified ...

Electrical arcs and, more generally thermal plasmas, are widely used in many applications and the understanding or the improvement of the corresponding processes or systems, often requires precise modelling of the plasma. We present, here, a double approach to thermal plasma modelling, which combines the scientific procedure with an engineering point ...

IEEE Transactions on Plasma Science, 1991
A review is given of the fundamental aspects involved in material processing using thermal plasma technology. The description of plasma generating devices covers DC plasma torches, DC transferred arcs, RF inductively coupled plasma torches and hybrid combinations of them. Emphasis is given to the identification of the basic energy coupling mechanism in

ICOPS 2000. IEEE Conference Record - Abstracts. 27th IEEE International Conference on Plasma Science (Cat. No.00CH37087), 2002
Summary form only given. In this paper, a brief overview of the history of thermal plasma modeling will be presented, including the effects of turbulence and deviations from local thermodynamic equilibrium in certain parts of thermal plasma systems. Based on some typical examples, the development over the past 60 years will be illustrated, restricted ...
