On the use of the metallic nozzle of a cutting arc torch as a Langmuir probe.
(2008)
The region inside the nozzle (bore diameter ≈1 mm) of a cutting arc torch is inaccessible to
most plasma diagnostics, and numerical simulations are the only means to find out the relative
importance of several physical ...
Hydrodynamic Model for the Plasma-Gas Flow in a Cutting Torch Nozzle.
(2004)
We present a simple hydrodynamic model to obtain the profiles of the relevant physical quantities along a nozzle
of arbitrary cross-section in a cutting torch. The model uses a two-zone approximation (a hot central ...
On the Use of Sweeping Langmuir Probes in Cutting Arc Plasmas—Part I: Experimental Results.
(2008)
The first study of Langmuir probes applied to cut ting arcs using a sweeping-probe system is presented. It is found
that, under a relatively broad range of experimental conditions
(changes in the probe material, in the ...
On the Double-Arcing Phenomenon in a Cutting Arc Torch.
(2011)
Transferred arc plasma torches are widely used in industrial cutting process of metallic
materials because of their ability to cut almost any metal and the very high productivity that
can be achieved with this technology ...
Investigation of the relevant kinetic processes in the initial stage of a double-arcing instability in oxygen plasmas.
(2018)
A numerical investigation of the kinetic processes in the initial (nanosecond range) stage of the
double-arcing instability was developed. The plasma-sheath boundary region of an oxygen operated cutting torch was considered. ...
On the dynamic behavior of the anode–arc–root at the nozzle surface in a non-transferred plasma torch
(2012)
The dynamic behavior of the anode–arc–root at the nozzle surface of a plasma torch
was experimentally investigated in this work. A gas (N2) vortex–stabilized non–transferred arc
torch with a thoriated tungsten rod (2wt ...
