Given the prospect of Science and Technology of the Islamic Republic of Iran in 1404 and consolidated its position in the field of micro and nanotechnology to earn 2% of the global market, research and development of this technology is important. It is based on a comprehensive plan adopted by the supreme council of the cultural revolution, the prioritization of science and technology from the perspective of both financial and human resources officials and managers, nanotechnology and and magnetic materials are ranked as A and C, respectively. A number of Artiman’s process development engineering company’s achievements in the field of micro and nano fluids properties are as follows:
Nanofluids have novel properties that make them potentially useful in many applications in heat transfer, including microelectronics, fuel cells, pharmaceutical processes, and hybrid-powered engines, engine cooling vehicle thermal management, domestic refrigerator, chiller, heat exchanger, in grinding, machining and in boiler flue gas temperature reduction. They exhibit enhanced thermal conductivity and the convective heat transfer coefficient compared to the base fluid. Knowledge of the rheological behavior of nanofluids is found to be very critical in deciding their suitability for convective heat transfer applications.
In analysis such as computational fluid dynamics (CFD), nanofluids can be assumed to be single phase fluids. However, almost all of new academic papers use two-phase assumption. Classical theory of single phase fluids can be applied, where physical properties of nanofluid are taken as a function of properties of both constituents and their concentrations. An alternative approach simulates nanofluids using a two-component model.Also, the ability to produce magnetic nanofluids scales grams and kilograms, with about half the cost of similar foreign example is offers.
