Departures from local thermodynamic equilibrium in cutting arc plasmas derived from electron and gas density measurements using a twowavelength quantitative Schlieren technique.
(2011)
A two-wavelength quantitative Schlieren technique that allows inferring the electron and gas
densities of axisymmetric arc plasmas without imposing any assumption regarding statistical
equilibrium models is reported. ...
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 ...
