This shows that the physical properties of nanofluids require further experimental studies. classified this material as Newtonian fluid. , and they presented that this material exhibit a non-Newtonian shear-thinning nature, on the other hand Khedkar et al. TiO 2–EG nanofluids have been examined for rheological properties by Cabaleiro et al. The rheological properties of nanofluids were investigated by many researchers and were published a few review papers.
ĭue to many of potential applications, nanofluids are extensively studied in many fields of science. The most frequently mentioned applications are all processes where there is a need to discharge large amounts of heat, for example: double pipe and multichannel heat exchanger, engine cooling, cooling of electronics, chillers, domestic refrigerator, solar water heating, cooling, and heating in buildings. Thanks to all of these properties, nanofluids have a huge potential in industry. Nanofluids have a higher thermal conductivity, higher electrical conductivity, and absorption of light. So much interests of nanofluids is due to their unusual thermophysical properties, completely different from the same materials in macro scale. As base fluids are usually used distilled water, oils, or alcohols, e.g. Nanofluids are identified as a suspension of solid particles with nanometric size (1–100 nm) in based fluids. This name was established by Choi in 1995. One of the most commonly studied group of nanomaterials are nanofluids.
Regardless of whether it is an increase in energy efficiency or miniaturization of devices or medical applications, many of the researchers believe that the nanomaterials are the future of technique and industry.
In an era of continuous technology development, scientists and engineers constantly strive to achieve better and better results in various fields of science and technology.
