  • Cathode-sheath model for field emission sustained atmospheric pressure discharges. 

    Cejas, Ezequiel; Prevosto, Leandro; Minotti, Fernando Oscar; Ferreyra, Matías; Chamorro, Juan Camilo (2021-03-16)
    The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple fluid model that takes into account non-local ionization. The effects of the ...

  • Interpretation of Voltage Measurements in Cutting Torches. 

    Prevosto, Leandro; Kelly, Héctor; Minotti, Fernando Oscar; Mancinelli, Beatriz; https://orcid.org/0000-0002-8771-9549; https://orcid.org/0000-0003-0577-9589 (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 ...

  • Numerical modeling of the gas breakdown development in the space–charge layer inside the nozzle of a transferred arc torch 

    Mancinelli, Beatriz; Prevosto, Leandro; Minotti, Fernando Oscar (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 ...

  • Numerical Modelling of a Cutting Arc Torch 

    Mancinelli, Beatriz; Minotti, Fernando Oscar; Prevosto, Leandro; Kelly, Héctor (Jan Awrejcewicz. INTECH, 2014-02-14)
    Plasma cutting is a process of metal cutting at atmospheric pressure by an arc plasma jet, where a transferred arc is generated between a cathode and a work-piece (the metal to be cut) acting as the anode . Small nozzle ...

  • On the use of the Prandtl mixing length model in the cutting torch modeling. 

    Mancinelli, Beatriz; Minotti, Fernando Oscar; Kelly, Héctor (2011-05-25)
    The Prandtl mixing length model has been used to take into account the turbulent effects in a 30 A high-energy density cutting torch model. In particular, the model requires the introduction of only one adjustable coefficient ...
