Schlieren technique applied to the arc temperature measurement in a high energy density cutting torch.
(2010)
Plasma temperature and radial density profiles of the plasma species in a high energy density cutting
arc have been obtained by using a quantitative schlieren technique. A Z-type two-mirror schlieren
system was used in ...
On the space-charge boundary layer inside the nozzle of a cutting torch.
(2009)
A numerical study of the space-charge sheath adjacent to the nozzle wall of a cutting torch is
presented. The hydrodynamic model corresponds to a collision-dominated sheath and does not
assume cold ions, so drift-diffusion-type ...
On the physical origin of the nozzle characteristic and its connection with the double-arcing phenomenon in a cutting torch.
(2009)
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 ...
