Modelling of an Atmospheric Pressure Nitrogen Glow Discharge Operating in High-Gas Temperature Regimes.
(2016)
A model of an atmospheric pressure nitrogen glow discharge in high-gas tem perature regimes is developed. The model considers a fairly complete set of chemical
reactions, including several processes with the participation ...
On the Gas Heating Mechanism for the Fast Anode Arc Reattachment in a Non-transferred Arc Plasma Torch Operating with Nitrogen Gas in the Restrike Mode.
(2015)
The present work provides a detailed kinetic analysis of the time-resolved
dynamics of the gas heating during the arc reattachment in nitrogen gas in order to
understand the main processes leading to such a fast reattachment. ...
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 ...
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 ...
Interpretation of Voltage Measurements in Cutting Torches.
(2015)
Anode-cathode and nozzle-cathode voltages, plenum pressure and gas mass flow measurements in a
low current (30 A) cutting torch, operated with oxygen gas, are used as inputs for an electrical model coupled
to a simplified ...
