Numerical Modelling of a Cutting Arc Torch
(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.
(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 ...
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 ...
