| Résumé : |
An inverse procedure is proposed to identify the macroscopic thermophysical properties of a two-phase heterogeneous during transient heat conduction processes. Macroscopic modelling is established using a volume averaging technique . In case of local thermal non-equilibrium, this leads to a two-equation model in which macroscopic properties are defined by six effective independent parameters. An identification procedure based on the Levenberg-Marquardt algorithm is proposed to identify the macroscopic properties in the case of stratified media. |
