Analysis of IC Engine Performance Using Nano Fluid as Coolant in Radiator – A Review

Abstract

Looking into the present day need of automobile heat disposal methods, many researchers are exploring the best
means to absorb and dissipate the heat from an engine in an efficient manner. Many automobile giants have invested
enormous time and money in this field to analyze overall heat transfer coefficient with variety of fluids. The recent
developments were use of nano particles in the base fluids as heat transfer medium. Water and ethylene glycol as
conventional coolants have been widely used in an automotive car radiator for many years. These heat transfer fluids offer
low thermal conductivity. With the advancement of nano technology, the new generation of heat transfer fluids called, “nano
fluids” have been developed and researchers found that these fluids offer higher thermal conductivity compared to that of
conventional coolants.
Nano fluid is a new type of heat transfer fluid with superior thermal performance characteristics, engineered by dispersing
metallic or non-metallic nano particles with a typical size of less than 100 nm in the conventional heat transfer fluids. Their
use remarkably augments the heat transfer potential of the base liquids. In this paper, many papers of cooling using nano
fluids made of different nano particles have been studied to check the possibilities of using these nano fluids in the IC eng ine
radiator cooling. It is found that Nano fluid is very effective in cooling than the conventional cooling fluid and using these
coolants in the IC Engine Radiator, good results of IC engine performance can be obtained.
