The Plasma ArcPlasma is a gaseous cloud composed of free electrons, positive ions, neutral atoms and molecules. It has been referred to as "the 4th state of matter" because of its unique properties. Its behavior involves complex interactions between electromagnetic and mechanical forces....
The plasma generator has an annular reaction chamber (2) with annular electrodes (3). A controllable injection nozzle (8) is tangential to the chamber. The pressure differential between gas in the chamber and in the injector is regulated. Ejection (6) of gas from the reaction chamber sets th...
Although progress has been made in the development of such models, the realistic simulation of the arc reattachment process, a central part of the arc dynamics inside plasma torches, is still an unsolved problem. This study presents a reattachment model capable of mimicking the physical reattachment...
The paper reports results of measurements of local plasma properties (electron density and temperature, radiance, and population density) in the recombining plasma flow of a high power (100 kW) quasi-steady MPD arc designed as a plasmadynamic laser source. The profiles of electron density and tem...
A plasma-arc cutting machine and a method of controlling the same, wherein a rise compensation circuit (39) and a transfer compensation circuit (44) consisting of a charge/discharge capacitor and a resistor are inserted in parallel between an electrode side connection (21) and a nozzle side ...
A plasma-arc process is disclosed for the production of powders of various chemical products, according to endothermic reactions, such as TiC and the like. The process consists essentially in carrying out, in a furnace with an anodic function without dissipative cooling, a series of steps comprisi...
Nozzle with a deflector for a plasma arc torch The invention relates to a nozzle () for a plasma torch, in particular a plasma cutting torch, the body of which has the general shape of an axisymmetric dish and includes an outlet orifice for the plasma gas jet, comprising a first exte.....

Plasma-arc technology was developed to dispose of chemical wastes from a chemical plant by the Institute of Mechanics, Chinese Academy of Sciences (CAS-IMECH). A pilot plant system with this technology was constructed to destroy two types of chemical wastes. The system included shredding, mixing...
V. GUTNIK,AN Morozov,NS Kurbyko,RB Kurbyko,AI Veis,IK Lind,MV Gutnik 摘要: A process for plasma are cleaning of metal surfaces in which movement of the arc plasma stream over the metal surface melts the surface layer subject to defects and removes it from the cleaning zone. The arc ...
