Keblinski et al. [71] and Eastman et al. proposed four possible mechanisms, e.g., Brownian motion of the nanoparticles, molecular-level layering of the liquid at the liquid/particle interface, the nature of heat transport in the nanoparticles, and the effects of nanoparticle clustering. Other groups have started from the nanostructure of nanofluids. A three component medium theory of a multiphase system was developed by above investigators which have assumed nanofluid as a composite in which the nanoparticles are assumed to form a core having enclosed with nanolayer treated as shell …show more content…

The technology of enhanced heat transfer has received strong attention over the last 3 to 5 decades [6]. Interesting characteristics of heat transfer when compared to the traditional fluids of heat transfer are the outcomes of these modern concepts of nanofluids. Lots of research work has been carried out in recent years on superior properties of the nanofluids for heat transfer particularly their convective heat transfer rates and their thermal conductivities [73]. Owing to these features of nanofluids, they have wide range of promising industrial applications such as in devices which exchanges the heat. Also this technique of heat transfer enhancement by means of nanofluids is equally applicable to application areas like electronics devices, bulky automobiles, power generation plants, refrigeration and air-conditioning systems, process industries, nuclear sectors and chemical industries and so on. Recently, the number of industrial application potential of nanofluids technology and their focus for specific industrial applications is increasing.
