Description
Summary:This paper presents the thermodynamic performance of automobile radiators using water (60%), ethylene glycol (40%)—fly ash nanofluids. The influence of nanofluid flow rate and concentration of fly ash on heat transfer parameters (such as overall heat transfer coefficient and heat transfer), energy transfer parameters (such as pumping power and performance index) and exergy performance parameters (such as exergy destruction rate and exergy efficiency) are studied. The results showed that the heat transfer characteristics, energy performance parameters and exergy performance parameters were significantly improved with increase in the concentration of fly ash in a base fluid (60% water–40% ethylene glycol) from 0.2 to 2% (by volume). The outcome of this research has the potential to replace conventional working fluids in heavy vehicle radiators. The concentration of fly ash with base fluid (60% water–40% ethylene glycol) was optimized to 2% (by volume).
