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. ...
Calculation of harmonic losses and ampacity in low-voltage power cables when used for feeding large LED lighting loads.
(2014)
A numerical investigation on the harmonic disturbances in
low-voltage cables feeding large LED loads is reported. A
frequency domain analysis on several commercially available LEDs was performed to investigate the ...
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 ...

(UTN FRVT, 2021)
En el presente trabajo se ha investigado el algoritmo que genera las competencias del ingeniero electromecánico, en la aplicación de software de modelado numérico y simulación. Se fundamenta este estudio en el impulso de ...
On the space-charge boundary layer inside the nozzle of a cutting torch.
(2009)
A numerical study of the space-charge sheath adjacent to the nozzle wall of a cutting torch is
presented. The hydrodynamic model corresponds to a collision-dominated sheath and does not
assume cold ions, so drift-diffusion-type ...
On the physical origin of the nozzle characteristic and its connection with the double-arcing phenomenon in a cutting torch.
(2009)
The nozzle current-voltage characteristic for a cutting arc is presented in this work. The
measurements are reported using a high energy density cutting arc torch with a nozzle bore radius
of 0.5 mm. The arc current was ...
