A Review of the Enhanced Heat Transfer Using Nanofluids

A small amount of nanoparticles those are uniform and stable when suspended in base fluid, thermal properties and dramatically expand the base fluid. Lubricants, hydraulic fluids used. The nanoparticles are made of various materials, for example, can be named the following materials: ceramic oxide, nitride ceramics, carbide ceramics, metals and synthetic materials such as alloy nanoparticles and nanofluids combination of solid-liquid in which metallic or nonmetallic nanoparticles. Too fine suspended particles alters the mobility features are the ability to increase heat transfer and heat transfer nanofluids show. According to previous research carried out, nano-fluid for increasing the thermo-physical properties is considered. Properties such as thermal conductivity, heat dissipation, viscosity and heat transfer coefficient compared to the base fluid displacement such as water and oil increases. Here the influence of several factors such as particle size, particle shape, particle type, operating temperature coefficient of thermal conductivity in particle concentrations also have been studied for the we review.
