In this paper thermal properties of conductive thin films on aluminium substrate are investigated using a phototyhermal method. In the first case the film thermal conductivity and heat capacity, the thermal contact resistance between thin and substrate and the convective heat transfer coefficient are simultaneously estimated. Secondly, the case of anisotropic thin fihns is studied. In that case, axial and radial thermal conductivities and the heat capacity of the thin fihn are simultaneously determined with the convective heat transfer coefficient. For the parameter estimation an inverse technique, based on Levenberg-Marquardt algorithm, is performed. [ABSTRACT FROM AUTHOR] |
