On the physical processes ruling an atmospheric pressure air glow discharge operating in an intermediate current regime
(2015-02-06)
Low-frequency (100 Hz), intermediate-current (50 to 200 mA) glow discharges were experimentally
investigated in atmospheric pressure air between blunt copper electrodes. Voltage–current
characteristics and images of the ...
Desarrollo de una diagnóstica refractiva para el estudio de plasmas no-térmicos de alta presión.
(UTN FRVT, 2017-03-09)
Este Proyecto Final consiste en la interpretación cuantitativa de la técnica Schlieren aplicada a un jet de plasma no térmico, cuasi-estacionario (50 Hz), y a presión atmosférica. El jet fue operado en régimen turbulento ...
Glow Discharge in a High-Velocity Air Flow: The Role of the Associative Ionization Reactions Involving Excited Atoms.
(2019)
A kinetic scheme for non-equilibrium regimes of atmospheric pressure air discharges
is developed. A distinctive feature of this model is that it includes associative ionization with
the participation of N(2D, 2P) atoms. ...
Plasma Cutting of Concrete: Heat Propagation and Molten Material Removal From the Kerf.
(2019)
An experimental investigation of heat propagation
in the case of plasma cutting of concrete is reported. The
experiments were carried out by using a high-enthalpy nitrogen
plasma jet generated in a dc vortex-stabilized ...
Improvement of growth and yield of soybean plants through the application of non-thermal plasmas to seeds with different health status.
(2019)
Soybean (Glycine max (L.) Merrill) is a globally important crop, providing oil and
protein. Diaporthe/Phomopsis complex includes seed-borne pathogens that affect
this legume. Non-thermal plasma treatment is a fast, ...
Ambient Species Density and Gas Temperature Radial Profiles Derived from a Schlieren Technique in a Low Frequency Non-thermal Oxygen Plasma Jet.
(2017)
A quantitative interpretation of the schlieren technique applied to a non-thermal
atmospheric-pressure oxygen plasma jet driven at low-frequency (50 Hz) is reported. The
jet was operated in the turbulent regime with a ...
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 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 ...
