Over the decade, researchers have developed new nanofluids for heat transfer applications. Little or no reports are made with the use of Agro-waste products as nanofluids. The sole purpose of this study is to evaluate the potential of nanoparticles (rice husk ash and graphene) in the thermo-physical enhancement of nanofluid for heat transfer applications. The study also highlights the synthesis of rice husk ash-graphene nanoparticles and the preparation of nanofluids. Particle characterisation was conducted using techniques such as SEM/EDXRF, XRD and TGA/DTA. Thermal conductivity, viscosity and heat capacity of the nanofluid were investigated for different particle concentration (0.1, 0.3 and 0.5wt.%) at temperatures (50, 60 and 70^oC) with deionized water as base fluid. The examine nanofluids shows better stability, an average maximum thermal conductivity enhancement of 71% at 70^oC and 0.5wt.% concentration for hybrid nanofluid. The excellent thermal properties of the nanofluids make them suitable candidates as nanofluids for heat transfer application.
