Abstract

Experimental measurements and computed results are reported, describing the behavior of a non-transferred arc plasma torch operating in a laminar mode, discharging into a nitrogen environment. The experimental measurements of the temperature fields in the vicinity of the torch exit, obtained using emission spectroscopy, were compared with theoretical predictions. The calculations were based on the solution of the axi-symmetric heat, mass, momentum, and species balance equations. The theoretical predictions were found to be in excellent agreement with measurement, with the error usually being in the 5–10% range and the maximum error being about 15%.
