Numerical investigation of the double-arcing phenomenon in a cutting arc torch
(American Institute of Physics, 2014-07)
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 ...
Investigation of the relevant kinetic processes in the initial stage of a double-arcing instability in oxygen plasmas
(American Institute of Physics, 2018-05)
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 physical origin of the nozzle characteristic and its connection with the double-arcing phenomenon in a cutting torch
(American Institute of Physics, 2009-12)
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 ...
Numerical modeling of the gas breakdown development in the space–charge layer inside the nozzle of a transferred arc torch
(IOP Publishing, 2012-06)
Double–arcing is a phenomenon that occurs when a transferred arc, flowing inside an electrically insulated nozzle, breaks into two separate arcs: one that connects the cathode with the nozzle, and another that connects the ...
Resonancia magnética en la evaluación de los anillos vasculares
(Sociedad Chilena de Pediatría, 1996)
An??lise das propriedades mec??nicas de juntas de a??o carbono estrutural soldadas pelo processo arco submerso com os arcos simples e duplo (Tandem-Arc)Mechanical properties assessment of structural carbon steel welded joints by means of submerged arc welding process with single arc and double arc (Tandem-Arc)

Fatigue assessment of a double submerged arc welded gas pipeline
(Elsevier, 2007-06)
An uncommon blow out in a 24″ diameter, 7 mm thick API 5L X52 gas pipeline was due to fracture at the longitudinal double submerged arc weld (DSAW). Fatigue cracks were found to have initiated from a large embedded weld ...
Modelling of the Plasma–Sheath Boundary Region in Wall-Stabilized Arc Plasmas: Unipolar Discharge Properties
(Springer, 2018-01)
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 ...
La novela conjetural
(Centro de Estudios de Teoría y Crítica Literaria, 2013-09)
Este trabajo consiste en una lectura de Sin embargo Juan vivía, de Alberto Vanasco, novela publicada en 1947 y precursora del nouveau roman francés. La lectura ensaya algunas hipótesis genéticas en relación con la prosapia ...
