Abstract
This study aims to examine the thermal conductivity of reduced Graphene Oxide solid dispersed in the Water fluid. For this mono-nanofluid, thermal conductivity was examined in particular temperatures (25–50 °C) and mass fractions (1–5 mg mL−1). Field emission scanning electron microscope test was done to observe the microstructure of the solid. The results showed the highest thermal conductivity enhancement (31.19%) in 5 mass%–50 °C. A novel correlation including 1.25% utmost deviation was predicted via curve-fitting on the 3D-output to tally the thermal conductivity of the nanofluid. Then, an artificial neural network with R2 = 0.99 was trained. Endmost, rGO/Water has satisfactory heat transfer capacity in thermal industries.
