Nanoparticles added to fluids increase their thermal conductivity to such an extent that it is several times that of fluids. Thus, nanofluids help in efficient heat transfer. In heat exchanger applications, it is highly desirable to increase the efficiency of heat transfer as much as possible. Nanofluids find extensive use in industrial processes for cooling engines, electronic appliances, and solar collectors.
In addition to these enhanced thermal properties, nanofluids have many other advantages, including power reduction required for pumping and the prevention of settlement-a fundamental concern for further performance. Their properties make the advanced nanofluids useful in EOR because of their ability to enhance fluid flow characteristics under reservoir conditions.
Besides this, investigations on nanofluids have been continuously increased in order to focus on the behavior of fluids with the influence of nanoparticles such as metal oxides, carbon nanotubes, graphene, and many more. Further exploration of the variables by providing research toward these variables would probably lead to a way to solve heat transfer in a more efficient manner, opening wide windows for the possible applications of nanofluids.
Nanofluids are probably the most promising advancement in thermal management technologies likely to revolutionize many industrial processes and find significant ways to improve energy efficiency in a wide range of applications.
