Assuming a regular geometry of dispersed phase (λ2) an integrated theory for the effective thermal conductivityλe of all kind of two-phase materials (including loose materials) is developed. The flux modification is carried out by considering the effective neighbouring interactions in the solution of Poisson’s equation. A comparison of calculatedλe values with the reported experimental results over a wide range of two-phase materials shows a good agreement.
