EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER PERFORMANCE OF VEHICLE RADIATOR USING AL2O3 NANOFLUID AS COOLANT

Abstract

Engine cooling system in I.C. Engine is the mechanism in which excess heat generated by the engine is absorbed by the coolant material. The coolant of an internal combustion engine plays a vital role in the performance of the engine. This topic is currently an active area of research in the field of nanotechnology. This study aimed to investigate the impact of 𝐴𝑙2𝑂3 nanoparticles of varying concentrations in the radiator of TATA Tiago 𝑋𝑍+under idle conditions. The 𝐴𝑙2𝑂3 nano-fluid was prepared via a two-step approach and characterized using UV-Vis spectroscopy. The results indicate an increase in heat transfer rate, thermal conductivity, and overall heat transfer coefficient. These findings suggest that the addition of 𝐴𝑙2𝑂3 nanoparticles in the radiator coolant can enhance the cooling efficiency of the vehicle.
