Modelling of the Plasma–Sheath Boundary Region in Wall-Stabilized Arc Plasmas: Unipolar Discharge Properties.
(2017)
A two-dimensional model of the non-equilibrium unipolar discharge occurring
in the plasma–sheath boundary region of a transferred-arc was developed. This model was
used to study the current transfer to the nozzle (1 mm ...
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 ...
Quantitative Schlieren Diagnostic Applied to a Nitrogen Thermal Plasma Jet.
(2018)
— A quantitative interpretation of the schlieren
technique applied to an atmospheric pressure, vortex-stabilized
nitrogen thermal plasma jet generated in a direct-current
nontransferred arc plasma torch (nitrogen gas ...
Effects of non–thermal plasmas on seed-borne Diaporthe/Phomopsis complex and germination parameters of soybean seeds.
(2018)
Diaporthe/Phomopsis (D/P) is a complex of seed-borne fungi that severely affects soybean (Glycine max (L.)
Merrill), one of the most important crops worldwide. Non-thermal plasma treatment is a fast, economic and ...
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 ...
