Abstract

Nanotechnology is interface technologies that span many different science and applications area.When engineering, science and technology are conducted at the nanoscale is called asnanotechnology. It is about 1 to 100 nm (nano-meter) where nano denotes the scale range of onebillionth of meter. Nanotechnology refers the properties of atoms and molecules measuring 0.1 to1000 nm. Nanofluids are nothing but suspension of nanometer sized particles in the base of fluid.The base fluid can be water based or non water based depending on the application. Commonnano particles are oxides, carbides, metals, carbon nano particles or nitrides. These fluids act asNewtonian fluids but in some cases these fluids do not work accurately hence non-Newtonianfluids are considered. Recent investigations on nanofluids, suggest that the suspendednanoparticles alter the transport properties and heat transfer characteristics of the suspension.This research summarizes recent trends on nanofluid heat transfer characteristics of Ag/H2O-EGnanofluids in free convection flows and identifies opportunities for future research.
