Abstract

Methods are presented for estimating effective transport coefficients of space-filling composites modelled by square, hexagonal, and cubic tessellations. These methods are particularly useful for composites whose phases differ in their individual transport coefficients by two or more orders of magnitude and whose transport properties are predominantly influenced by the connectedness of the phases. Problems of interest could include evaluation of effective diffusion coefficients of incompatible polymer blends, effective thermal conductivities of porous media, effective electrical conductivities of metal-filled polymers, and effective elastic moduli of disordered composites.
