Abstract—A mathematical model has been proposed for calculating the effective Thermal Conductivity of nano colloidal dispersions by incorporating a thermal conductivity profile for the interfacial layer. The present model has been successfully applied to the colloidal dispersions containing rod shaped nanoparticles as well as those containing spherical nanoparticles. The results have also been compared with other existing models.

Index Terms—Thermal conductivity, nanofluids, colloidal dispersion and interfacial layer.
