摘要：

This paper deals on the quantification of the energy transferred between and electric arc plasma and a copper anode material. The aim consists in an experimental tool development and a validation of the numerical method. The experimental tool is based on the conjugate gradient method and allows obtaining, through some punctual temperatures in the anode by thermocouples, the total temperature field in the material and the applied flux at its surface. In a first time the experimental device is presented. It consists on a transferred arc configuration, in an argon gas for current intensities around one hundred amps. Then the main lines of the mathematical method are presented and tested through two heat flux profiles. Before applying the method to the experimental setup, a parametric study is made on the captor's positions and on their number. Finally the tool is applied to our experimental configuration in order to quantify the flux at the anode surface and to determine the temperature field in the material. In the described configuration, for a current intensity equal to 90A, the deduced flux is applied on a radius of 5mm with a maximum value of 3.5 x 10(7) W.m(-2).
