Synthesizes, characterization, measurements and modeling thermal conductivity and viscosity of graphene quantum dots nanofluids

The present study is aimed to measure the thermophysical properties of graphene quantum dots (GQDs) nanoparticles that dispersed in water, ethylene glycol and water-ethylene glycol mixture (60:40) as base fluids. The presence of GQDs enhance the viscosity and thermal conductivity of nanofluids considerably. The maximum thermal conductivity enhancement reaches up 53%, 21% and 18% for the nanofluid containing 0.5% GQDs at 50 °C in water, ethylene...
