Researches in heat transfer have been carried out over the previous several decades, leading to the development of the currently used heat transfer enhancement techniques. The water and ethylene glycol as conventional coolant have been widely used in an automotive radiator in many years. With the advancement of nanotechnology, a coolant are invented which is known as “nanofluids”. The Researchers found that these fluids offer higher thermal conductivity compared to that of conventional coolants. The study is focused on the performance evaluation of the louvered fin based tube automotive radiator using nanofluids as coolant. The compact radiator is basically used in automotive vehicles. In the present work, relevant input data, nanofluid properties and empirical correlations is taken from previous literatures and is analyzed the fluid flow and cooling capacity characteristics of a compact automotive radiator operated with the use of nano fluid like Si C based fluid. An automotive radiator (louvered fin type) model is modeled on modeling software CATIA V5 and performance evaluation is done on pre-processing software ANSYS 14.0. Present study outline that the nano fluids may effectively use as coolant in automotive radiators to improve the performance. The temperature and velocity distribution of coolant and air are analyzed by using Computational fluid dynamics environment software CFX. Results have shown that the rate of heat transfer is better when nano fluid (Si C + water) is used as coolant, than the conventional coolant.
