An equation has been theoretically derived for the effective thermal conductivity of a medium with anisodiametric particles. The case of the thermal conductivity of particles being much in excess of that of the binding medium is analyzed in detail. The possibility is shown for the particle shape parameters to be determined from the dependence of the effective thermal conductivity on the filler volume fraction. The effective thermal conductivity of solutions filled with metallic powders differing in nature and dispersivity has been studied experimentally. The predicted results agree satisfactorily with the experimental data.
