An Updated Review on Improving Radiator Efficiency Using Nanofluid Coolants

The automotive industry is always looking for new and creative ways to boost a car’s performance and efficiency. In order to maintain optimal engine performance and avoid overheating, which can result in mechanical problems and decreased fuel efficiency, efficient heat dissipation is essential. Because of their improved heat transmission capabilities, nanofluid suspension fluids with nanoscale particles have become a viable substitute for conventional coolants in car radiators. This paper examines practically all of the studies that have been conducted in this field that are available in the literature. The author collects information on nanoparticle materials and sizes, as well as the volume, basefluid, concentration, Reynolds number (Re) and Nusselt number (Nu) employed in investigations. The nanofluid concentration often used in car radiators generally varies from 0.01 to 5%. The extent of this range might fluctuate based on the particular application and the nature of the nanoparticles used. Generally, higher nanoparticle concentrations result in a more pronounced enhancement in heat transfer and an increased need for pumping power. Utilizing nanofluids results in a decrease in the energy consumption related to pumping due to the enhanced heat conduction capability of nanofluids.
