Recently application of nano-technology in medicine and cancer therapy has generated a lot of interest in thermal properties of bio-nanofluid such as blood with nanoparticles suspension. In this study effective thermal conductivity of blood with suspension of Al2O3 nanoparticles as a bio-nanofluid was studied. A two-step model based on parallel mixture rule, thermal resistance concept and Maxwell-type equations was developed. First a model based on the parallel mixture rule and thermal resistance concept was used to predict the blood cells thermal conductivity. Then a model for the effective thermal conductivity of the bio-nanofluid was developed. It was shown that the results of the proposed model for the blood thermal conductivity agree well with the available data in the literature.
