Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

In recent years, the use of nanofluids has increased due to their distinctive properties. They have been recognized as a suitable alternative to common heat transfer base fluids. One of the most critical challenges related to nanofluids that have been affected by the commercialization debate is their sustainability, which, if unraveled, can be used industrially. Nanofluids are utilized in cooling equipment such as heat exchangers and renewable energies such as solar cells as heat transfer fluid. Using nanofluid in heat transfer applications has enhanced the base working fluid's heat transport properties and reduced the heat transfer system area, material, and size. The techniques for nanofluid stability enhancement and stability evaluations, such as zeta potential, electron microscopy, and photographic techniques for sedimentation, were reviewed. The existence of nanoparticles in nanofluid enhances the thermo?physical properties of the base fluid, resulting in a faster heat transfer rate than the base fluid. The aim of this paper is review some recent achievements in nanofluid stabilization and research on the affecting parameters on the thermal properties of nanofluids. Finally, the use of nanofluids in cooling devices has been reviewed. Increasing heat transfer, reducing heat transfer time, reducing the size of heat exchangers, and finally growing energy and heat efficiency could be the most significant achievements of this review. The results of this study showed that the degree of stability increases with increasing ultrasonic time and adding surfactant. The parameters affecting the thermal conductivity of nanofluids include concentration, temperature, particle fluid, type of base fluid, nanoparticles, and how to prepare nanofluid, which tried to use the latest research available in the present study.
