ABSTRACT

An experimental study is presented on an argon transferred arc configuration for current intensity around few hundred amps. Spectroscopic, thermocouples and calorimetric measurements are made respectively in the plasma in the anode material and in the calorimetric system. The measurements allow to determine boundary conditions for the model (heat transfer coefficient), and by the use of an inverse method to obtain the temperature field in the material and the flux applied to its surface. In the same time the model applied in the same configuration gives results compared with experimental ones. A good agreement is found on the plasma temperatures allowing to compare the others quantities. The comparison of the theoretical flux with the experimental one presents some differences that we can attribute to a wrong estimation of the heat transfer coefficient. Nevertheless, the inverse method build allows to obtain interesting results [1].
