Numerical study of heat transfer characteristics of graphite nanofluid in flat tubes

Performance of Graphite and Al2O3 nanofluids mixed in the base fluid - Ethylene Glycol: Water (60:40) as radiator working fluid in a three-dimensional flat-tube taken from Chrysler minivan is compared through computational analysis. Properties are calculated from mathematical correlations developed...

description	Performance of Graphite and Al2O3 nanofluids mixed in the base fluid - Ethylene Glycol: Water (60:40) as radiator working fluid in a three-dimensional flat-tube taken from Chrysler minivan is compared through computational analysis. Properties are calculated from mathematical correlations developed from experiments on nanofluids and used for numerical analysis. The model is validated for average heat transfer coefficient and Nusselt number under Laminar regime for Reynolds number 1000, 1500, and 2000 using Al2O3 for 1% and 10% concentrations with the result in the available literature. Then, the average heat transfer coefficient and average Nusselt number of Al2O3 and Graphite are compared for 1% and 10% volumetric concentrations, and the results are presented. The average heat transfer coefficient of Graphite is higher than Al2O3 with a percentage increase of 3.29% for 1% concentration and 5.17% for 10% concentration.
