V. CONCLUSION

By studying and analyzing various literature we studied that replacing of the conventional coolant by the modern NANOCOOLANT will definitely prove comparatively effective. The results which will be obtained by calculation studied above is the evidence of increase in the efficiency of the radiator. The following inferences can be drawn successfully after reviewing various research paper from reputed journal:

The heat transfer rate of nanofluid is greater than that of conventional coolant as the conductivity of the Alumina is higher than the simple coolant. The size of the radiator is reduced in the case if we want same heat transfer rate as that of the conventional coolant. Hence it becomes possible to improve the aerodynamic shape of the car which would reduce the air drag. The reduced air drag, improved heat transfer rate, better engine cooling reducing the average fuel consumption. The volumetric efficiency of the engine cylinder is also improved due to better and faster cooling. The most important the NOx emission is also considerably reduced as the engine temperature is reduced below 110*C.

Thus we finally conclude that it is very beneficial in all-round aspects improving the overall vehicle performance and covering all important aspects.
