Nanofluids for Heat Transfer Augmentation in Heat Exchangers—An Overview of Current Research

In the heat exchanger system, nanofluids are used to improve the effectiveness of passive heat transfer methods. Many researchers have demonstrated the wide range of engineering applications for nanofluids. In this study, heat transfer in heat exchangers is enhanced by the use of nanofluids. Nanofluids have a better thermal conductivity in heat exchangers than conventional fluids. When compared to pure liquids, the mixing stream had superior heat transfer properties because of the nanosized particles in nanofluids. Despite the fact that many heat exchangers outperform others, nanofluids are the only ones that do so due to their thermal conductivity and faster heat transfer rates. This review paper looks at and discusses the findings and observations of various research groups on nanofluids as an employed way. Furthermore, the conclusions of various authors are evaluated, and points of argument are discussed. As a result, using nanofluid in a heat exchange system is likely to improve thermal transmission performance.
