Analysis of thermal performance of a car radiator employing nanofluid

چکیده مقاله

In this study, thermal performance of a car radiator with employment of Ethylene Glycol/copper nanofluid in disparate environmental conditions has been investigated. The governing equations for heat transfer in the car radiator have been written and solved by using a generated computer code in different environmental states and the changes in the output nanofluid temperature have been studied. It has been shown that by increasing the values of volume fraction of nano-particles and also, Reynolds number of inlet air, one can observe a raise in the values of overall heat transfer coefficient of the air side and the rate of heat transfer. Furthermore, it is observed that by adding nano-sized particles to the coolant fluid in radiator, one can significantly reduce its output temperature. In addition, it has been demonstrated that by adding 5% of nano-particles to the coolant fluid, thermal performance of the radiator in a hot weather of 50˚ C can be better than its performance in the weather of 20˚C.
