Effects of non-thermal plasma technology on Diaporthe longicolla cultures and mechanisms involved.
(2021-01-05)
BACKGROUND: The Diaporthe/Phomopsis complex (D/P) is a group of soybean seed-borne fungi. The use of chemical fungicides,
either for seed treatment or during the crop cycle, is the most adopted practice for treating fungal ...
Cathode-sheath model for field emission sustained atmospheric pressure discharges.
(2021-03-16)
The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple
fluid model that takes into account non-local ionization. The effects of the ...
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 ...
Cathode-sheath model for field emission sustained atmospheric pressure discharges
(2021)
The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple
fluid model that takes into account non-local ionization. The effects of the ...
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 ...
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 ...
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 ...
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. ...
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 ...
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. ...
