  • Abstract

Traditionally forced convection heat transfer in a Automobile radiator is performed to cool circulating fluid which consisted of water or a mixture of water and anti-freezing materials like ethylene glycol (EG). In this paper, the heat transfer performance of binary mixture EG+ water (50 %) volume concentration. Furthermore, different amounts of Al2O3 nano particle have been added into these base fluids and its effects on the heat transfer performance of the Automobile radiator have been determined experimentally. Air Reynolds number has been changed in the range of 84391-91290 and the fluid inlet temperature has been constant for all the experiments and mass flow rate of the coolant flowing through the radiator. The results demonstrate that nanofluids clearly enhance heat transfer compared to their own base fluid. In the best conditions, the heat transfer enhancement of about 70% compared to the base fluids has been recorded.
