Abstract: Heat transfer enhancement is showing a relatively positive effect on compact heat exchanger performance in automobile applications.Heat transfer enhancement helps to increase the thermal efficiency of the heat exchanger, allowing it to transfer more heat in less time.This helps to reduce the fuel consumption of the vehicle and increase its efficiency.Present researches focus on the enhancement of high-performance heat exchangers in heavy cargo vehicles in the automobile sector.Compact heat exchangers having low space occupancy and high performance coolant blends need to be studied for heat transfer applications.The work is a case study of blends comparison with and without Nano addition to check the variation after adding 1% Al2O3 to locally available coolants like TFC Anti-freeze coolant, MFC, Castrol.The experiments were run at 60℃ and 80℃ and 1.765, 3.53 bar pressure taken as full flow and pressure drop conditions.The Sonication process was also explained to evaluate the thermal properties of coolant blends before and after NANO-addition.The addition of NANO-Al2O3 with MFC gave good results when compared with the others.
