Abstract

Graphene oxide is generally used in hydrogen storage, energy conversion, lens, and flexible rechargeable battery electrode. Silica is one of the most plentiful families of materials, which has potential to be an excellent choice for industrial applications due to its low-cost production, high specific surface area, and also its hydrophilicity. Hybrid nanofluid (HN) is one of nanofluid types in which more than one solid particle dispersed in a fluid. In this paper, after preparation of graphene oxide/silicon dioxide/water hybrid nanofluid, thermal conductivity (TC) was studied and numerically modeled. Then, to study phase and structural analysis, X-ray diffraction analysis and dynamic light scattering analysis were employed. After that, scanning electron microscope was used to study microstructural observation of nanoparticles. TC measurements of HN were taken at volume fractions of 0.05–1.0% and at temperature ranges of 25–50 °C. Thermal conductivity enhancement of 26.93% was measured at 1.0 vol.% fraction in 50 °C temperature. For numerical modeling, new correlation has been offered (R2 = 0.9), and further, artificial neural network has been modeled (R2 = 0.999). For offered correlation, 1.48% deviation and for trained model, 1.26% deviation were calculated. Totally, GO–SiO2–H2O HN has acceptable heat transfer potential.
