Abstract. The surge in global energy demand necessitates efficiency improvements in thermal systems. Nanofluids have emerged as promising working fluids because of their improved thermal performance. This investigation assesses the thermal and pumping behavior of graphene–water nanofluids with 0.01–0.10 vol.% graphene nanoplatelets and varied sodium dodecyl sulphate concentrations over 10–70°C. It also explores the benefit of these suspensions for applications operating under laminar and turbulent flow conditions. The thermophysical data were used to assess laminar effectiveness via the thermal conductivity‐to‐viscosity ratio (Cλ/Cμ > 0.25) and turbulent performance via the Mouromtseff number (Mo > 1), alongside heat‐transfer (FoMₕₑₐₜ transfer) and pumping (FoMₚᵤₘₚ) figures of merit. Results show that higher graphene loadings (0.1 vol.%) with lower surfactant levels maximize heat‐transfer performance, especially at elevated temperatures, while the lowest pumping performance occurs at 10 °C with 0.10 vol.% graphene and higher surfactant. These findings reveal that both graphene concentration and temperature critically influence nanofluid effectiveness for enhanced thermal applications.
