“…c o m / l o c a t e / i c h m t thermal conductivity enhancement was achieved by a fluid containing '0.05 wt.% MWCNTs-3 wt.% Ag' composite. Chen et al [22] examined the effect of combining MWCNTs and Fe 2 O 3 nanoparticles on thermal conductivity of water based nanofluids. Their results revealed that the thermal conductivity enhancement of the nanofluid containing 0.05 wt.% MWCNTs and 0.02 wt.% Fe 2 O 3 nanoparticles was 27.75%.…”

In this paper, an experimental study on the effects of temperature and concentration on the thermal conductivity of f-MWCNTs-Fe 3 O 4 /EG hybrid nanofluid is presented. The experiments were carried out for solid volume fraction range of 0 to 2.3% in temperatures ranging from 25°C to 50°C. The results revealed that the thermal conductivity ratio enhances with increasing the solid volume fraction and temperature. Results also showed that, at higher temperatures, the variation of thermal conductivity ratio with solid volume fraction was more than that at lower temperatures. Moreover, the effect of temperature on the thermal conductivity ratio was more noticeable at higher solid volume fractions. The thermal conductivity measurements also showed that the maximum thermal conductivity ratio was 30%, which occurred at temperature of 50°C for solid volume fraction of 2.3%. Finally, for engineering applications, based on experimental results, a precise correlation was suggested to predict the thermal conductivity of f-MWCNTs-Fe 3 O 4 /EG hybrid nanofluids.

“…Iron oxide/multi-walled carbon nanotube (Fe2O3/MWCNTs) nanofluid was synthesized by Chen et al, [33] and the thermal conductivity of the hybrid nanofluid was evaluated by varying the volume concentration of the iron oxide in the hybrid nanofluid. 27.7% enhancement in thermal conductivity was obtained with 0.02 wt % Fe2O3 and 0.05% MWCNTs, the enhancement was due to Iron oxide (Fe2O3) aggregate locally on MWCNTs surface their by forming chains along the carbon nanotubes.…”

Hybrid nanofluid is a new nanotechnology fluid that is synthesized by dispersing two different nanoparticles into conventional heat transfer fluid. Recently, researchers have indicated that hybrid nanofluids can effectively substitute the convectional coolant especially those working at very high temperatures. In this paper a comprehensive literature on the synthesis of hybrid nanoparticles, hybrid nanofluid and thermal performance of hybrid nanofluid have been compiled and reviewed.

“…Apart from the van der Waals, depletion, and steric stability forces, the Brownian force [213,214], buoyancy force [215], hydration force [216], and interphase resistance [217] may also contribute to the dispersion stability of nanofluids under specific conditions.…”

Applying nanomaterials and nanotechnology in lubrication has become increasingly popular and important to further reduce the friction and wear in engineering applications. To achieve green manufacturing and its sustainable development, water-based nanolubricants are emerging as promising alternatives to the traditional oil-containing lubricants that inevitably pose environmental issues when burnt and discharged. This review presents an overview of recent advances in water-based nanolubricants, starting from the preparation of the lubricants using different types of nanoadditives, followed by the techniques to evaluate and enhance their dispersion stability, and the commonly used tribo-testing methods. The lubrication mechanisms and models are discussed with special attention given to the roles of the nanoadditives. Finally, the applications of water-based nanolubricants in metal rolling are summarised, and the outlook for future research directions is proposed.
