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 ...
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. ...
