On the physical processes ruling an atmospheric pressure air glow discharge operating in an intermediate current regime
Prevosto, Leandro; Kelly, Héctor; Mancinelli, Beatriz; Chamorro, Juan Camilo; Cejas, Ezequiel (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 ... -
Physicochemical Properties and Time Stability of Plasma Activated Water by a Liquid-Cathode Glow-Type Discharge in Air: The Effect of Air Confinement.
Santamaría, Brenda; Ferreyra, Matías; Chamorro, Juan Camilo; Cejas, Ezequiel; Fina, Brenda; Prevosto, Leandro; ; https://orcid.org/0000-0001-7046-2188; https://orcid.org/0000-0002-9833-1662; https://orcid.org/0000-0001-5386-5516; https://orcid.org/0000-0002-8771-9549 (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 ... -
Plasma Cutting of Concrete: Heat Propagation and Molten Material Removal From the Kerf.
Chamorro, Juan Camilo; Prevosto, Leandro; Cejas, Ezequiel; Milardovich, Natalio; Mancinelli, Beatriz; Fischfeld, Gerardo (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 ... -
Quantitative Schlieren Diagnostic Applied to a Nitrogen Thermal Plasma Jet.
Chamorro, Juan Camilo; Prevosto, Leandro; Cejas, Ezequiel; Kelly, Héctor (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 ... -
Quantitative Schlieren Diagnostics Applied to a Millisecond Pulsed‑DC Hybrid Discharge in Atmospheric Pressure Air.
Cejas, Ezequiel; Chamorro, Juan Camilo; Prevosto, Leandro (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 ...
