Volume: 1 Issue: 1
Year of Publication: 2019
Authors: D.V.Raghunatha Reddy, Anjanna Matta



Abstract

In this present study, a numerical analysis is developed to evaluate the base fluid and mixture ratios influencing on the heat transfer coefficient and flow characteristics of nanofluids in the turbulent range of Reynolds number employing in the investigation. This analysis formulated with the help of Eddy diffusivity equation of Van Driest. The properties of Aluminum dioxide (Al2O3) nanofluid with a low fluid Ethylene Glycol (EG) -Water (W) mixture of 60:40 ratio is employed in a wide range of concentrations of 0.5% to 2% on a bulk temperature range of 20oC to 90oC.The influences of density and temperature effect on heat transfer coefficients are determined. The maximum concentrations for which the heat transfer enhancement can attain are estimated to be 1.5% and 2.0% at 30oC and 80oC respectively under turbulent range. The temperature effect and concentration ratios are influencing on a heat transfer coefficient of nanofluids were analyzed and observed that the heat transfer coefficients enhances with concentration and decreases with temperature.
