Cooling systems are
needed for internal combustion engines to operate efficiently. The fluid
traditionally used to transfer heat in cooling systems is a mixture of ethylene
glycol (EG) and water (W). These fluids generally exhibit an effect that
extends the operating temperature range and limits the heat output. On the
other hand, nanofluids are known to increase the thermal capacity of liquid
suspensions and have been studied in many experimental and numerical studies.
This study examines the effects of nanofluids instead of currently used
EG-Water on an actual vehicle. Three different nanofluids (TiO2, Al2O3,
and SiO2) were used, and the concentration ratios of these fluids
were determined as 0.1% and 0.2%. A real vehicle engine cooling system with a
volume of 1400 cm3 operating at an average of 2000 rpm was used in
the studies. Fluids that are widely studied in the literature were taken into
account when selecting nanofluids. The results showed that SiO2
achieved the highest performance, with an increase of 15% compared to the base
fluid. On the other hand, it was observed that increasing the concentration
value of TiO2 exhibited a lower performance increase compared to
other nanofluids. Finally, it has been observed that the operating temperature
range of nanofluids affects.
