The experimental work to boost forced heat transfer performance in an Al 2 O 3 , SiC-Water+ ethylene glycol nanofluid radiator was discussed in this paper. In this analysis, different volume fractions of nanofluids in the range of 0.01 to 0.1 percent were prepared and sonicated for 2 hours using an ultrasonic sonicator to achieve stable suspension with the incorporation of Al 2 O 3 , Sic nanoparticles into the water. The maxium-performable heat transfer was found to be 50 percent higher than water at a fraction of 0.1 per cent. The effective thermal conductivity of the nanofluid is increased with increased particle concentration, which helps to boost radiator heating efficiency. The rate of heat flow ranges from 3 to 12 lpm. It is noted that the efficiency of heat transfer has increased with an increase in flow rate.
