AN ANALYTICAL EXTENSION OF THE RECIPROCITY FUNCTIONAL APPROACH TO ESTIMATE THERMAL CONTACT CONDUCTANCES BETWEEN DIFFERENT MATERIALS USING TRANSIENT MEASUREMENTS
要約
This work deals with the thermal contact conductance estimation in the interface between two different solid objects. This paper presents an extension of the reciprocity functional method that allows using transient measurements. The reciprocity functional is a fully analytical, non-iterative and non-intrusive technique, which requires the definition of some auxiliary problems for each unknown function to be estimated. In this work, the auxiliary problems were solved analytically, reducing the inverse problem solution to a simple algebraic equation. Some test problems are presented, using synthetic noisy measurements, with good results.
