“…At 2.0% volume concentration, nanofluids viscosity increased from 20.5 to 33.8% and 29.8 to 53.4%, respectively, for the mixture of W/BG at 80:20 and 70:30 in the range of 30 to 80 °C. In another study, Abdolbaqi et al [22] also found a similar trend for the viscosity of SiO2/W:BG-based green nanofluids with concentration and temperature. For the mixture of W/BG at 80:20 and 70:30, the viscosity of SiO2/W:BG nanofluids increased from 16.02 to 28.9% and 17.3 to 37.8%, in the temperature range of 30 to 70 °C and 30 to 60 °C, respectively.…”

“…Relative to the mixture of PG:water (W), the BG:water (W) mixture provided 7.5% enhancement in thermal conductivity at the same ratio. In addition, Abdolbaqi et al [ 21 ] and Abdolbaqi et al [ 22 ] also conducted a study on the thermal performance of colloidal suspensions of TiO 2 /BG:W and SiO 2 /BG:W nanofluids, respectively. In the study, the thermal conductivity was enhanced by up to 12.6% and 7.2% for the TiO 2 /BG:W and SiO 2 /BG:W nanofluids, respectively.…”

“…In addition, the pulse wire evaporation (PWE) single-step method is also one of the most outstanding methods to prepare the nanofluids. Abdolbaqi et al [ 22 ] stated that this technique required a high voltage pulse to be directed through a thin wire, then the wire will evaporate into plasma due to the non-equilibrium heating in a short period. This plasma is then condensed to nano-sized powder upon interaction with inert gas, such as Ar or N 2 , and combined with the nanofluids that are poured into an exploding bottle installed in the PWE device to form hybrid nanofluids.…”

Many studies have shown the remarkable enhancement of thermo-physical properties with the addition of a small quantity of nanoparticles into conventional fluids. However, the long-term stability of the nanofluids, which plays a significant role in enhancing these properties, is hard to achieve, thus limiting the performance of the heat transfer fluids in practical applications. The present paper attempts to highlight various approaches used by researchers in improving and evaluating the stability of thermal fluids and thoroughly explores various factors that contribute to the enhancement of the thermo-physical properties of mono, hybrid, and green nanofluids. There are various methods to maintain the stability of nanofluids, but this paper particularly focuses on the sonication process, pH modification, and the use of surfactant. In addition, the common techniques to evaluate the stability of nanofluids are undertaken by using visual observation, TEM, FESEM, XRD, zeta potential analysis, and UV-Vis spectroscopy. Prior investigations revealed that the type of nanoparticle, particle volume concentration, size and shape of particles, temperature, and base fluids highly influence the thermo-physical properties of nanofluids. In conclusion, this paper summarized the findings and strategies to enhance the stability and factors affecting the thermal conductivity and dynamic viscosity of mono and hybrid of nanofluids towards green nanofluids.

Progress in technology and industrial developments demands the efficient and successful energy utilization and its management in a greater extent. Conventional heattransfer fluids (HTFs) such as water, ethylene glycol, oils and other fluids are typically low-efficiency heat dissipation fluids. Thermal management is a key factor in diverse applications where these fluids can be used, such as in automotive, microelectronics, energy storage, medical, and nuclear cooling among others. Furthermore, the miniaturization and high efficiency of devices in these fields demand successful heat management and energy-efficient materials. The advent of nanofluids could successfully address the low thermal efficiency of HTFs since nanofluids have shown many interesting properties, and the distinctive features offering extraordinary potential for many applications. Nanofluids are engineered by homogeneously suspending nanostructures with average sizes below 100 nm within conventional fluids. This chapter aims to focus on a detail description of the thermal transport behavior, challenges and implications that involve the development and use of HTFs under the influence of atomistic-scale structures and industrial applications. Multifunctional characteristics of these nanofluids, nanostructures variables and features are discussed in this chapter; the mechanisms that promote these effects on the improvement of nanofluids thermal transport performance and the broad range of current and future applications will be included.
