Abstrakt

This paper presents a comparison between theoretical and experimental studies in a cutting plasma torch. Calculations were made with a laminar compressible model with supersonic flows. By using visible spectroscopy we measured densities and temperatures from time integrated luminosities, that were corrected from the effect of plasma fluctuations.
