Abstract
The Equilibrium Molecular Dynamics (EMD) simulation is applied for computing the thermal conductivity (TC) of pure ethylene glycol nanofluids containing graphene nanosheets, through Green-Kubo framework. The effects of concentration (graphene sheet1 [length= 1.475nm and breadth=0.85198nm], sheet2 and sheet3) and temperature (285-313K) on TC and specific heat have been studied. The thermal conductivity of the nanofluids increases with temperature as well as with loading fraction of the nanosheets. The results are in conformity with previous findings. The specific heat curves show that it increases slightly with temperature for both the base fluid and nanofluids. But, it decreases with loading fraction of graphene nanosheets. It can be concluded that the enhancement in thermal conductivity or diminishment of specific heat are related to the rearrangement of the EG base fluid around the C-atom of graphene.
