Experimental Study of Heat Transfer Enhancement in Automobile Radiator Using Nanofluids.

the research article presented the forced convective heat of transfer in water solution base nanofluid have carried out experimentally and comparison is made with use of pure water as working medium in automobile radiator. The presented study has been carried out for the different concentrations of nanoparticles with having base fluid of water. The concentration for the nano particles is taken as 0.05, 0.08, 0.1, 0.3and 0.5 vol. %. The results are noted for the mass flow rates of working fluid between 3 to 5 LPM with increment of 1 LPM. Also the temperature varies from 45oC to 55oC with increment of 5oC.Initially the experiment demonstrated on the pure water as working fluid. The results of study shows improvement in heat transfer coefficient with nanofluids. For this study the copper oxide (CuO), aluminium oxide (Al2O3) and ferric oxide (Fe2O3) are used and finally the comparison is made.
