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 ...
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 ...
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 influence of the nozzle length on the arc properties in a cutting torch
(2009)
In this work, an experimental study on the influence of the nozzle geometry on the
physical properties of a cutting arc is reported. Ion current signals collected by an electrostatic
probe sweeping across a 30 A oxygen ...
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 ...
Non‑Thermal Plasmas Afect Plant Growth and DNA Methylation Patterns in Glycine max.
(2021)
Non-thermal plasmas (NTP) are partially ionized gases that represent a promising technology for seed treatment to enhance
seed health while promoting germination and vigor in a fast, cost-efective, and eco-friendly way. ...
