Numerical modelling of physical properties and processes in an electric arc stabilized by a water vortex (steam torch) has been summarized in this review paper. One-fluid MHD equations are numerically solved for an axisymmetric thermal plasma flow inside a discharge chamber of the steam plasma torch.

Attenuation of microwaves by plasma torches
ICOPS 2000. IEEE Conference Record - Abstracts. 27th IEEE International Conference on Plasma Science (Cat. No.00CH37087), 2002Summary form only given. An experiment has been conducted in a rectangular waveguide to study the effectiveness of plasma torches on microwave absorption. Three torch modules are mounted on the bottom wall of a rectangular X-band waveguide (1 in./spl times/2 in.), so that the plasma produced by the torch crosses the path of propagation of the microwave

With acetone as a catalyst in an argon discharge plasma, it is observed that localized high-density anode spots can be formed at sharp edges in the plasma. By placing the sharp edge on top of a small permanent magnet, the current which is attracted to the spot can locally burn a piece of metal beneath the sharp edge.

The plasma torch is a poorly understood, little known prodigy among the physical modalities used in medicine. It is unknown to most physicians because it is presently an experimental tool, references in the medical literature are sparse, and it masquerades under several aliases.

Reviews of Physics in Technology, 1971
The design principles and construction are first presented and the important problem of plasma stability and the methods of maintaining stability, over a range of conditions and in different gases, are then considered. The power supplies and the various methods that have been used to initiate the torches are described.

Arcs, plasma torches and applications
IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2003Summary form only given, as follows. The applications of arcs and plasma torches can be roughly classified in two domains: electrical engineering and thermal (or chemical) processes. In the first category we can consider circuit-breakers, arc lamps and some aspects concerning lightning. In the second category, we can distinguish metallurgical processes

Ion implantation for plasma torches
Vacuum, 2002Abstract It has been shown before that the erosion of a cathode is related to the condition of its surface, particularly with respect to its composition. The composition of the surface seems to affect different parameters, including the work function of the surface.

The basis of the physical processes in the RF plasma torches and parameters of the RF plasma torches will be considered in this chapter. They are based on the two models—equilibrium and nonequilibrium plasmas, as well as the experimental results.

Inductively Coupled Plasma Torches
2013We investigate in this chapter another type of application using eddy currents. An Inductively Coupled Plasma torch (commonly referred to as ICP) is a technical device used to analyze a given sample (gas, solid or liquid prepared as an aerosol) by injecting it in a plasma (generally made of argon) (see Fig. 10.1).

Supersonic Flow Ignition by Plasma Torch and H2/O2 Torch
Journal of Propulsion and Power, 2004The effectiveness of an H 2 /O 2 torch igniter, which injects H 2 /O 2 combustion gas, and a plasma torch igniter in promoting ignition of an H 2 /air mixture within a supersonic combustor was investigated analytically and experimentally. First, bulk temperature and bulk radical concentration in an O 2 plasma torch igniter were estimated by ...
