Enhancing Thermal Conductivity and Heat Transfer using Graphene Nanofluid

Abstract

Due to their low density and inherent thermal conductivity in compared to metals or metal oxides, carbon nanostructures among other nanoparticles exhibit better thermal conductivity. The ability of graphene Nano fluids to transmit heat has been studied in this work through a review of the findings of several studies. The current techniques for making graphene nanofluids have been summarized, along with several characteristics including viscosity, concentration, particle size, and temperature that have an impact on thermal conductivity. The convective heat transfer capabilities of graphene nanofluids have also been subjected to a careful analysis. The study shown that employing graphene nanofluids as a working fluid through a tube channel can improve heat transfer with considerable results. There hasn't been any research on the effects of graphene Nano fluids on facing steps and corrugated surfaces, according to the literature.

Formulation of Graphene Nanoplatelets Water-Based Nanofluids using Polyvinylpyrrolidone (PVP) as Surfactant

“…Graphene nanoplatelets (GNP), one of several forms of nanoparticles, have drawn a lot of interest because of their remarkable thermal, mechanical, and electrical capabilities [13]. A study by Ridha et al, [14] shows that heat transfer can be improved by utilizing graphene nanofluids as a working fluid in a tube channel. While prior studies have explored the potential of nanofluids in enhancing the performance of PV/T systems, this study distinguishes itself through a comprehensive investigation into the use of GNP as heat transfer enhancers.…”
