The word nanotechnology is new, but it’s existence of the functional devices and structure of nanofluid devices are not new in this world. In 1905, experimental data on diffusion theory showed that the molecule has nanometer diameter, which is considered as a notable landmark in the scientific history of nanotechnology. After the investigations made by Choi and Eastman the situation was changed. Choi and Eastman while working at Argonne National Laboratory have reformed this nanotechnology with their metallic powder partiecle having nanosize and carbon nanotube suspensions in 1995…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.
