In the present work, heat transfer performance of radiator (Heat Exchanger) was studied as a function of heat transfer by using water, engine coolant and Al2O3-water nanofluid. The Al2O3-water nanofluid was characterized by X-ray diffraction, scanning electron microscope and ultraviolet-visible spectroscopy. The Al2O3 nano particles with specification of 2.5 wt% concentration, cubic size and 60 min. probe sonication were used. The mass flow rate of all the three coolants is kept in the range of 0.5 to 5 lit/min, regulated by Rotameter. Temperature difference at inlet and outlet of Radiator (Heat Exchanger) is recorded for all the three coolants with the help of Thermostat. The temperature difference versus discharge graph plotted for water, engine coolant and nanofluid revealed that the highest heat transfer (thermal conductivity) is for Nanofluid followed by coolant and water. The enhancement in thermal conductivity reflects that the nanofluids could be appropriate for cooling applications.
