Analysis of heat exchanger (radiator) using Al2O3 and SiO2 nanofluid

Conventional heat transfer fluids like water and engine oil are widely employed in the automobile radiator in recent times. However, to boost the thermal performance of the system, lots more is required from the heat transfer fluid perspective. One of the important techniques to reinforce heat transfer is that to boost the thermal conductivity of working fluid with inclusion of nano-sized solid particles as additives. this paper includes the studies to judge the performance of the heat transfer characteristics of water based nanofluid as a coolant for car radiator. The metal oxide nanoparticles Al2O3 and SiO2 are dispersed into base fluid at 10% volume concentrations. The thermo-physical properties of both nanofluids are calculated and assessed with the assistance literature work. The mass stream rate of nanofluid within the radiator tubes is 4 lit/min. With the assistance of ANSYS FLUENT 19.2 solver, the outlet temperature, convective heat transfer coefficient, Heat Transfer effectiveness and Nusselt numbers for the concentration of every nanofluids is investigated by the mass rate of flow.
