Numerical Modelling of a Cutting Arc Torch
(Jan Awrejcewicz. INTECH, 2014-02-14)
Plasma cutting is a process of metal cutting at atmospheric pressure by an arc plasma jet,
where a transferred arc is generated between a cathode and a work-piece (the metal to be
cut) acting as the anode . Small nozzle ...
On the use of the double floating probe method to infer the difference between the electron and the heavy particles temperatures in an atmospheric pressure, vortexstabilized nitrogen plasma jet.
(2014)
Sweeping double probe measurements in an atmospheric pressure direct current vortex-stabilized
plasma jet are reported (plasma conditions: 100 A discharge current, N2 gas flow rate of 25 Nl/min,
thoriated tungsten rod-type ...
Numerical investigation of the double-arcing phenomenon in a cutting arc torch.
(2014)
A numerical investigation of the double-arcing phenomenon in a cutting arc torch is reported.
The dynamics of the double-arcing were simulated by using a two-dimensional model of the gas
breakdown development in the ...
Diagnostics of cutting arc plasmas.
(2014)
An over-view of several remote and invasive diagnostics to characterize cutting arcs
at the nozzle exit-anode gap as well as inside the nozzle is reported. A briefly description of the
experimental set-ups, together with ...
