TEMPERATURE DISTRIBUTION IN A LOW MASS FLUX ARGON PLASMA JET
Abstract
The temperature distribution in a 12-kw A plasma jet was determined. The jet was a low-mass-flux high-enthalpy type and exhausted into the atmosphere. The measurements were made with a grating spectrograph and temperatures were determined by the 2-line method. A calorimetric heat exchanger and a radiation receiver were used to establish an energy balance for the plasma torch. The existence of thermodynamic equilibrium was established for a 60-kw N plasma jet. This was done by using the rotational band spectra of carbon impurities present in the jet. The experimentation and the evaluation of the spectroscopic measurements is discussed in considerable detail, since this method is not yet as widely known as other methods of temperature determination.
