Interpretation of Voltage Measurements in Cutting Torches.
(2015)Anode-cathode and nozzle-cathode voltages, plenum pressure and gas mass flow measurements in a low current (30 A) cutting torch, operated with oxygen gas, are used as inputs for an electrical model coupled to a simplified ... -
Diagnostics of cutting arc plasmas.
(2014)An over-view of several remote and invasive diagnostics to characterize cutting arcs at the nozzle exit-anode gap as well as inside the nozzle is reported. A briefly description of the experimental set-ups, together with ... -
Numerical modeling of the gas breakdown development in the space–charge layer inside the nozzle of a transferred arc torch
(2012)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 ... -
Efecto sobre la tensión de rotura en flexión de la altura de la sección en elementos estructurales de pino ponderosa.
(UTN FRVT., 2023)La influencia de las dimensiones de la sección transversal en la resistencia a la flexión es un efecto contemplado en distintos reglamentos de estructuras de madera. En las normativas europeas y de Argentina la ... -
Effects of the Plasma-Activated Water on the Quality and Preservation of Fresh-Cut Lettuce.
(2023)— The effect of the application of plasma-activated water (PAW) on the quality and preservation of fresh-cut lettuce is reported in this article. PAW was produced by using a liquid cathode air discharge. The average ... -
Numerical Simulation of the Voltage–Current Characteristic of an Atmospheric Pressure Discharge: The Glow‑to‑Arc Transition.
(2024)The glow-to-arc transition of a convection-stabilized atmospheric pressure air discharge is numerically investigated. Two separate models are considered: a one-dimensional axisym metric time-dependent fuid model of the ... -
Quantitative Schlieren Diagnostics Applied to a Millisecond Pulsed‑DC Hybrid Discharge in Atmospheric Pressure Air.
(2022)The gas temperature of a hybrid discharge in atmospheric pressure air is investigated by using quantitative schlieren imaging. The discharge is stabilized in a pin-to-plate electrode geometry and operated in a millisecond ... -
Indigo Carmine Degradation in Water Induced by a Pulsed Positive Corona Discharge in Air: Discharge and Postdischarge Effects.
(2022)In recent years, one of the fastest growing technological applications in the field of nonthermal plasmas is the degradation of organic contaminants of water. In this work, the degradation of indigo carmine (IC) in water ... -
On the reduction of the third-order harmonic losses in low–voltage power cables used for feeding large LED and CFL lighting loads.
(2017)An experimental investigation of diversity factors for LED (light emitting diode) in combination with CFL (compact fluorescent lamps) and LED lamps is presented in this paper. Attention was paid to the reduction of ... -
Effect of in–package cold plasma treatments on the quality of minimally processed apples.
(2023)Cold plasma technology is being increasingly used for food preservation and, incipiently, for minimal processing of fruit. Therefore, the objective of this work was to study the effect of in-package cold plasma (generated ... -
Physicochemical Properties and Time Stability of Plasma Activated Water by a Liquid-Cathode Glow-Type Discharge in Air: The Effect of Air Confinement.
(2023)Nonthermal discharges in atmospheric pressure air in contact with water produce large amounts of reactive species in the gas phase that can enter into the water by diffusion, thus inducing the formation of secondary ... -
Non-thermal plasma application improves germination, establishment and productivity of Gatton panic grass (Megathyrsus maximus) without compromising forage quality.
(2022)Megathyrsus maximus (Gatton panic) is a tropical grass highly valued both for its use as forage and for its biofuel potential. A major constraint in establishing pastures of this cultivar is the low viability and germination ... -
Non-thermal plasma as emerging technology for Tribolium castaneum pest-management in stored grains and flours.
(2022)The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), is a major secondary pest on wheat stored in metal bins, silo-bags and is also frequently found in wheat products such as flour. Non-thermal ... -
Non‑Thermal Plasmas Afect Plant Growth and DNA Methylation Patterns in Glycine max.
(2021)Non-thermal plasmas (NTP) are partially ionized gases that represent a promising technology for seed treatment to enhance seed health while promoting germination and vigor in a fast, cost-efective, and eco-friendly way. ... -
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 ... -
On the influence of the nozzle length on the arc properties in a cutting torch
(2009)In this work, an experimental study on the influence of the nozzle geometry on the physical properties of a cutting arc is reported. Ion current signals collected by an electrostatic probe sweeping across a 30 A oxygen ... -
