Simple model for thermal conductivity of nanofluids using resistance model approach

Abstract: In this work thermal conductivity of the suspension is modeled using resistance model approach. This model considers Brownian motion and interfacial layer as well as a new mechanism where proposed by considering nanoparticles as liquid-like particles. The model can be used for estimation of upper and lower limits of nanofluid thermal conductivity, without any adjustable parameter. Thermal conductivity data of CuO nanofluids are obtained experimentally and the results show that the model is consistent to data. This model has been used for determination of various mechanisms'' portions on thermal conductivity of nanofluids. The results are consistent with our knowledge about nanofluids'' thermal conductivity mechanism. [Copyright &y& Elsevier]
