Experimental quantification in thermal plasma medium of the heat flux transferred to an anode material

Résumé

This paper is devoted to a plasma characterization with an experimental quantification of the energy transferred to the anode material in a transferred arc configuration. After spectroscopic measurements in an argon plasma medium, measurements in the anode material were performed using thermocouples. The flux applied by the plasma medium to the anode material was deduced from experimental measurements and the use of an iterative inverse method, the conjugate gradient method. The optimal temperature sensor positions were deduced from a previous theoretical study showing the suitability of the method for flux quantification using recommendations exposed in the paper. The measurements were made for various values of the current intensity around 100 A leading to fluxes close to 107 W m-2.
