Abstract
In This study, an experimental study has been carried out to investigate the effect of adding Al2O3, Al, and Cu nanoparticles to the base fluid (water) on enhancement of heat transfer and heat transfer coefficients in a car radiator. The experiments have been done for distilled water and 3 types of nanofluids with different concentrations (0.5, 1 and 2 vol. %) and in various operational conditions (temperature, flow rate, etc.). Thermal Conductivities of these fluids have been measured experimentally and other thermo-physical properties like density and viscosity are calculated using related models. Results depicted that addition of nanoparticles to the base fluid increases its thermal conductivity, density and viscosity, and decreases its specific heat capacity. The performance evaluation of nanofluids in a radiator system showed that will dramatically enhances the heat transfer and decreases the heat transfer area required, so it is highly recommended to use them in such systems.
