A Comparative Study of Classical Models for Effective Thermal Conductivity of Nanofluids Filled with Al2O3/CuO Nanoparticles
Liquids with suspended nanoparticles called nanofluids are likely to be the future heat transfer fluids since their thermal conductivities are significantly higher than that of base fluid even when the nanoparticle concentrations are negligibly small. In the present work a comparative study of classical models such as Maxwell model, Russell model, Nielsen model and Heat transfer model have been studied for effective thermal conductivity (ETC) of nanofluids filled with Al2O3/CuO nano particles. The classical models have been modified by introducing a nanolayer for calculating ETC. Prediction of ETC of nanofluids filled with Al2O3/CuO nanoparticles is done through these modified classical models. The enhancement in the ETC of nanofluids may be due to the distribution of volume fraction at the liquid particle interface. Artificial neural network (ANN) technique has also been used for calculating the ETC of nanofluids. The results of the models have been compared with the results of ANN technique and available experimental results in literature.
