Abstract
It is experimentally demonstrated that the nanofluids prepared using CuO nano particles improved the radiator thermal performance when used as a coolant. A mixture of water and EG in the ratios of 80:20 by volume is employed as base fluid for the preparation of CuO nanofluids in the present investigation. Volume concentration of CuO is varied between 0.07 and 0.023% in the base fluid for heat transfer experiments. Experiments are conducted with a flow rate ranging between 600 and 900 LPH through the radiator. In this investigation, it is observed that the radiator thermal performance improved with the flow rate in the range considered. Augmentation of heat transfer rate up to 53% is observed in comparison to the base fluid in the range of flow rates considered in this investigation. Effect of flow rate of nanofluids on the Nusselt number is presented graphically taking the nanoparticle concentrations as a parameter.
