抄録

The effective thermal diffusivities of porous materials are calculated with correlative equations for effective thermal properties. To check these calculated results, the effective thermal diffusivities were measured using the Flash-Method by a finite element method under the same operating conditions for the porous materials. The calculated results agree closely with the data from the Flash-Method by numerical analysis.<BR>From the results of temperature distribution calculated numerically, the factors which influence the effective thermal diffusivity in the porous materials are mainly void fraction and the thermal conductivity ratio of two phases. It is pointed out that the standard for application of the Flash-Method to effective thermal diffusivities of porous materials is not only a ratio of size between a sample and vacant space, but also affected with the thermal conductivity ratio of two phases and the void fraction.
