Conclusion
Aluminum is most common material used in manufacturing of radiator. Aluminum decreases the overall weight of radiator. There are many advantage of circular cross
section of radiator like increased heat transfer of fluid to surrounding, also the circular cross section has fewer perimeters. Various cross section like rectangular have problem of stress concentration while it is eliminate in circular cross section tubed radiator. Manufacturing of circular shape is easy.
Material requirement for circular tubed cross section radiator is less and thus the overall cost of product decreases. In this paper comparison between Aluminum and Copper alloy radiator model is
carried out. The copper radiator has higher temperate drop than aluminum radiator. But the Aluminum radiator is much economical than copper radiator. Aluminum radiator model is better for low cost & low weight and exhibit better corrosion resistance.
In this paper pure water and water based Nanofluid coolant are used in automobile radiator for measuring heat transfer coefficient at different concentration and
temperature. Nanofluid has better thermo physical properties & higher thermal
conductivity so higher heat transfer coefficient, and by using nanofluid because of this
radiator of reduced size can be used for same amount of heat removal which ultimately
responsible for better car performance and increased fuel economy. The higher % of
particle of Al2O3 in water can increase the heat transfer rate of automobile radiator.
This paper highlights the two step method used for preparation of nanofluid- Al 2 O 3 -
Water+Ethylene Glycol prepared by two step method. In two step method 10.5litres of
distilled water mixed with 4.5 liters of ethylene glycol and it is used as based fluid.
Oscar ultra sonicator is used for preparation of nanofluid. Al 2 O 3 nanoparticle in
water+ethylene glycol base solution increase the heat transfer rate of radiator. The
degree of heat transfer increases depends on the amount of nano particle mixed with
the water+ethylene glycol.
CuO/water & Al 2 O 3 /water have better thermophysical properties. CuO has higher
density & thermal conductivity than Al 2 O 3 . But CuO was not concluded as economical
alternative.
