Comparative Numerical Analysis of ZnO and Ag/ZnO Nanofluids Flowing Through Automobile Radiator

In the last few decades, nanotechnology has played a vital role in introducing heat transfer into the industry. Currently, maximum research has been conducted on heat transfer to increase the rate of heat transfer and to increase the efficiency of heat transfer devices pertaining to vehicles, such as heat exchangers and automobile radiators. In this study, the numerical investigation has been performed to analyse the heat transfer of the nanofluid ZnO and a novel Ag/ZnO flowing through the radiator. The analysis is performed for pressure drop and Nusselt number for each simulation. The results were presented, including temperature distribution, pressure drop, Nusselt number, Reynolds number, and heat transfer rate. HTC of Ag/ZnO is enhanced by 34.68% more than ZnO at 0.1% volume concentration. At same volume concentration, pressure drop of Ag/ZnO nanofluid is reduced by 18.03%. It is observed Ag/ZnO nanofluid appears to be more effective than ZnO nanofluid.
