Abstract: Nanofluids are new generation of thermo fluids. Researchers are attracted towards their application in various thermal energy systems. Before employing nanofluids in the heat exchangers, it is necessary to ensure superior thermo physical properties of nanofluids. In the present work, different thermo physical properties of nanofluids like thermal conductivity, viscosity, specific heat and density have been studied for a wide range of volume concentration (0.25-2.0 %) and temperature (30-60°C). TiO2 / H2O and CeO2 / H2O nanofluids show good stability for 0.25-2.0 volume %. The temperature range 30-60°C is considered because above 60°C the convection heat transfer may affect the accuracy of measurements. De-ionized water (D.I. water) is considered as base fluid. TiO2 /H2O and CeO2 /H2O nanofluids show superior thermal properties as compared to D.I. water.
Keywords: Nanofluids, Thermal conductivity, Specific heat, Density.
