Lots and Lotz of good stuff.

ARC
COLUMN STABILIZED BY WATER VORTEXFigs.
2 and 3 show curves calculated from (2) and (3) for three plasma mediums - argon. nitrogen andwater.
"Principle of stabilization of arcs by liquid wall can be utilized for stabilization of long arc columns at very
low flow rates of plasma gas. Thus, plasma jets with high temperatures can be generated in torches with
liquid stabilization. In water plasma torches the oxygen-hydrogen plasma is produced, high content of
hydrogen results in high enthalpy and sound velocity of plasma. Water-stabilized plasma torches thus
generate plasma jet with extremely high plasma temperature and flow velocity."
