“…Nanofluids are stable suspension of the nanoparticles in a base fluid like water, ethylene glycol and industrial oils. Nanoparticles can be metallic like Silver [1] and Copper [2], metal oxide like Al 2 O 3 [3] and CuO [4,5] and nonmetallic like SiC [6] and carbon nanotubes (CNT) [7,8]. Nanofluids containing nanoparticles exhibit enhanced the heat transfer characteristics [9][10][11].…”

“…Since nanoparticles have large surface area, its interaction with the surrounding medium can overcome the difference in density and hence can remain stably suspended. The nano-size of the particles also overcomes the drawbacks of microparticles such as clogging of the channels, abrasion and pressure drop (Kumar et al 2009). …”

“…Among the several approaches for the synthesis of nanofluids, the one-step chemical method is found to be the one which can overcome the downsides of other techniques like agglomeration during storage, partial dispersion, need for liquids with high-boiling points and expensive equipments (Zhu et al 2004a;Eastman et al 2001;Kumar et al 2009). Literature reveals that there are only a few reports on this technique (Kumar et al 2009;Liu et al 2006;Zhu et al 2004a).…”

One-step method has been employed in the synthesis of copper nanofluids. Copper nitrate is reduced by glucose in the presence of sodium lauryl sulfate. The synthesized particles are characterized by X-ray diffraction technique for the phase structure; electron diffraction X-ray analysis for chemical composition; transmission electron microscopy and field emission scanning electron microscopy for the morphology; Fourier-transform infrared spectroscopy and ultraviolet-visible spectroscopy for the analysis of ingredients of the solution. Thermal conductivity, sedimentation and rheological measurements have also been carried out. It is found that the reaction parameters have considerable effect on the size of the particle formed and rate of the reaction. The techniques confirm that the synthesized particles are copper. The reported method showed promising increase in the thermal conductivity of the base fluid and is found to be reliable, simple and cost-effective method for preparing heat transfer fluids with higher stability.

Refrigeration applications are generally based on vapor compression systems and represent a significant contribution to global climate change. While refrigeration is instrumental to the development of humanity, it is predicted that an increase in the number of refrigeration applications will worsen the issue of climate change. Hence, energy-efficient systems with a lower contribution to global warming are required. In the last years the research and development of new working fluid technologies and methodologies have provided an opportunity for the transition from vapor compression systems based on fluorine fluids to more sustainable alternatives. For instance, the potential advantages and drawbacks of hydrofluoroolefins are being investigated, and mixtures with hydrofluorocarbons are being developed to find trade-off solutions. Furthermore, the applications of hydrocarbons are being extended to installations that require a lower refrigerant charge. Lower flammability refrigerants require new flammability and risk analysis studies to determine their possible hazard. Heat and mass transfer phenomena studies are being carried out for new pure and mixed refrigerants. Ejectors are being studied to increase energy performance in particular applications. Alternative technologies based on renewable energy or solid states, such as solar cooling or magnetic refrigeration, are being developed and integrated into new processes. The integration of phase change materials and slurries is a promising new alternative. Finally, nanoparticles and nanofluids have opened an entirely new world of possibilities. The available literature on these topics is still in its early stages and these working fluids, technologies, and methodologies are not considered mature. However, there is significant potential to improve energy efficiency as well as the operation and capacity of these new approaches.
