“…On contrary to the significant enhancement as reported by Vajjha et al, [6], an experimental investigation on the overall heat transfer coefficient of CuO/water nanofluids in a car radiator reported a mere enhancement of 6-8%. The contradictory conclusions denoted about the effect of nanoparticle suspension on Nusselt number in a car radiator system is also reported by Lotfi et al, [22].…”

In the present work, an experimental investigation has been conducted to analyse the effects of graphene-nanoplatelet (GnP) suspension on the thermal performance of automotive radiator. GnP nanofluids are prepared by dispersing the nanoparticles in distilled water with a concentration of 0-0.3 vol.%. The thermophysical properties of water-GnP nanofluid have been studied with different volumetric concentrations and temperatures. The present study shows that convective heat transfer performance of the automotive radiator could be enhanced by increasing the nanoparticle suspension, heating power, air flow and Reynolds number. The maximum thermal performance enhancement of 275% is achieved for 0.3 vol.% GnP nanofluid at the highest rated heating power. It is also evident that the suspension of nanoparticle has the most significant effect in enhancing the convective heat transfer of automotive radiator, followed by the effects of heating power, air velocity and Reynolds number.

“…The number of studies on convective heat transfer of nanofluids in automotive radiator is relatively scarce as compared to the other heat transfer applications [22]. In up-to-date literature, most of the study of graphene-based nanofluid in automotive radiator employs the mixture of water and EG as the basefluid [7,24,25].…”

“…Improving heat transfer through the use of smaller heat exchangers to cool engine water can lead to a decrease in the vehicle's weight, which in turn can reduce fuel usage and lower emissions. 2,3 For many years, traditional liquids such as water, oil, ethylene glycol, and others have been used for heat transfer in industrial and commercial applications. However, their low thermal conductivity has impeded rapid heat transfer and disposal.…”

Multiwalled carbon nanotubes (MWCNTs) were employed as added particles for nanofluids in this practical investigation. To identify the most appropriate nanofluid for cooling PVT systems that are functional in the extreme summer environment of Baghdad, the parameters of base fluid, surfactant, and sonication time used for mixing were examined. Water was chosen as the base fluid instead of other potential candidates such as ethylene glycol (EG), propylene glycol (PG), and heat transfer oil (HTO). Thermal conductivity and stability were important thermophysical qualities that were impacted by the chosen parameters. The nanofluid tested in Baghdad city (consisting of 0.5% MWCNTs, water, and CTAB with a sonication period of three and a quarter hours) resulted in a 119.5, 308, and 210% enhancement of thermal conductivity (TC) for water compared with EG, PG, and oil, respectively. In addition, the nanofluid-cooled PVT system had an electrical efficiency that was 88.85% higher than standalone PV technology and 44% higher than water-cooled PVT systems. Moreover, the thermal efficiency of the nanofluid-cooled PVT system was 20% higher than the water-cooled PVT system. Finally, the nanofluid-cooled PVT system displayed the least decrease in electrical efficiency and a greater thermal efficiency even when the PV panel was at its hottest at noon.

“…Several strategies are used to enhance the dispersion of carbon nanotubes, [14] the use of surfactants [15,16] and surface functionalization are some of these [17] . Covalent functionalization has not been deeply studied for dispersion in fuel, most studies used commercial CNT or its oxidized form, [18] but the results are not profoundly discussed.…”

Carbon nanotubes functionalized with long‐chain compounds were obtained. Using different characterization techniques, such as thermogravimetric analysis (TGA), infrared spectroscopy (FTIR), x‐ray photoelectron spectroscopy (XPS), Raman spectroscopy, surface area analysis and electron microscopy (EM), it was possible to characterize the carbon nanotubes, verifying the presence of the added aliphatic chains, as well as the formation of the amide bonds, the morphological and structural changes of the material. Those functionalized with oleylamine showed dispersion stability in Colombian commercial diesel for at least 70 days, by visual inspection; using UV‐Vis absorbance and particle size measurement it was determined that in the first hours after the generation of the dispersion there was sedimentation of a portion of the material to reach an equilibrium point in which 75 % of the particles continued in suspension.
