  • Abstract:
  • Nanofluids are new heat transfer coolant. This study is mainly on the application of water based Al2O3 nanofluid at lower concentration in a radiator. Al2O3/water nanofluid is used because it is boardly used in the research area due to requirements such as homogeneity and continuous suspension without any chemical change of the base fluid. In this work two step method is used for preparation of the nanofluid. Al2O3 nanoparticles with an diameter of 50 nm was dispersed in pure water at different volume concentrations (0.1 & 0.2 vol. %) without any dispersant or stabilizer. Flow rate is varied in the range of 2 lit/min to 5 lit/min and inlet coolant to the radiator has a constant temperature which is changed at 50, 60 and 70 degree celsius. The results we get that the convective heat transfer coefficient is more with nanofluid. And the heat transfer coefficient increases with increase in flow rate and with increase in nanoparticle concentration.
