1. INTRODUCTIONNanomaterials have seen tremendous concentration in the last two decades due to their unique properties that find potential applications in many fields of science and technology. It has grown explosively over the last decade, due to the increasing availability of methods, nanomaterial synthesis, and characterization and manipulation tools. Nanotechnology makes us believe that we would have the ability to create anything that we could precisely define. The synthesis of nanomaterials is another key issue. General approaches in the synthesis of nanomaterials involve vapor, liquid or solid state pathways or their clever combinations. Size effects are an essential aspect of nanomaterials. Size effects are of two types: one concerns specific size effects and the other size scaling applicable to relatively larger nanostructures. The synthesis of nanomaterials includes control of size, shape and structure. Ultra-high performance cooling is one of the most important needs of the automotive industries. So the recent advancement for efficient cooling is nanofluids. Viscosity is one of the most important factors used for the correct selection of oil required in a lubrication system and flash point and pour point are also the properties related to the quality of the oil. functionality in different working conditions. The concentration of nanoparticles has a large effect on the functionality of nanolubricants. The nanofluid is not a simple liquid-solid mixture; The most important criterion of nanofluid is stable agglomerate-free suspension for long periods without causing any chemical change in the base fluid. Nano-sized particles prevent particle agglomeration and sedimentation of pa...... middle of paper ......es", International Journal of Scientific & Engineering Research, volume 4, number 5, May- 2013 ISSN 2229- 5518.13.
