Abstract

     In this work, we present a numerical study to determine the thermal conductivity and two heat transfer coefficients concerning the studied system. An identification of these parameters is simultaneously led. These parameters are identified starting from the simulated and measured temperatures. The method is based on a convolution integral inversion technique and on a direct model of the Boundary Element Method. In this frame, the functional to minimize can be pondered by sensitivity coefficients.
