Experimental Study of Graphene Oxide Nanofluid for Heat Transfer Application

Abstract

Nanofluids, with their high thermal conductivity and prospective applications, offers a lot of potential in the heat transfer enhancement phase. The thermal conductivity of a graphene oxide (GO) nanofluid is proposed to be synthesised, characterized, and studied. GO was characterized using XRD, FTIR, and SEM methods. A modified hummer technique was used to successfully synthesize graphene oxide (GO). It was tested at different temperatures (30-50oC) and volume concentrations (0.02-0.1 vol. percent). At 0.1 volume percent, the augmentation of thermal conductivity was revealed to be 32.45 percent, which is superior to the base fluid (ethylene glycol). This nanofluid has a great deal of potential as a replacement for sophisticated fluids utilized in heat transfer applications for sustainable development.
