Dispersed materials & problems of homogenisation

Abstract

We have obtained the physical features of an isotropic and homogeneous environment on both theoretical and experimental levels, in particular when thermal features are linked through the λ = a ρC_p relation. As far as dispersed samples are particularly concerned, this largely used correlation is not confirmed in out-of balance non-homogeneous samples (transitional rate of flow /regime). So, we have developed, by electronic analogy a theoretical model that allows us to study the thermal performance and to discuss conditions of homogenization in such material.
