Abstract: In the present work, a mathematical model for predicting effective thermal conductivity of nanofluids containing spherical nanoparticles is developed. This model takes into account the effects of an interfacial nanolayer formed by liquid molecule layering on the particle liquid interface as well as microconvection caused by thermal motion of nanoparticles. The present model has been proposed in order to calculate the effective thermal conductivity of nanofluids. The model accounts for the enhancement in effective thermal conductivity of a nanofluid with respect to the suspended nanoparticles size, volume fraction, temperature and thermal conductivities of the nanoparticle and base fluid. The results show that the prediction capability of the developed model is good by the way of comparison with the existing recent experimental data.
