The aim of this work is to present some recent developments in the identification technique of thermophysical properties of insulating materials from transient conductive experiments. The non linear, time varying, inverse heat conduction problem is solved by using a suitable version of the Kalman filter. This last is one of the more general and powerful stochastic methodology available in the field of parameter estimation. Several transient experiments performed with the European standard reference for thermal conductivity of insulators (resin bonded glass fiber board BCR 64) have shown that the confidence bound of the reconstructed thermophysical properties is comparable to that given by standard methods.

Abstract

The aim of this work is to present some recent developments in the identification technique of thermophysical properties of insulating materials from transient conductive experiments. The non linear, time varying, inverse heat conduction problem is solved by using a suitable version of the Kalman filter. This last is one of the more general and powerful stochastic methodology available in the field of parameter estimation. Several transient experiments performed with the European standard reference for thermal conductivity of insulators (resin bonded glass fiber board BCR 64) have shown that the confidence bound of the reconstructed thermophysical properties is comparable to that given by standard methods.
