“…An enhancement of about 27% was gained at a temperature of 20°C and 0.2 vol.%. In this study, the size of sheets was about 0.5-2 lm [21] which was found to be higher than reported by Sen Gupta et al [35]. The larger sheets size will become near each other and acts as conducting percolation path followed percolation theory.…”

“…However, the Brownian motion is caused by the random motion of the small-sized nanosheets. Micro convention caused by Brownian motion will become dominates and hence, increasing the thermal conductivity with increasing the temperature [21,35]. Furthermore, rising the temperature will decrease the viscosity and increase the random motion of nanoparticles (Brownian motion) and hence enhancing the thermal conductivity [29].…”

A nanofluid consists in a liquid suspension of nanometer-sized particles. These fluids may contain (or not) surface-active agents to aid in the suspension of the particles. Nanometer-sized particles have higher thermal conductivity than the base fluids. Oxides, metals, nitrides, and nonmetals, like carbon nanotubes, can be used as nanoparticles in nanofluids. Water, ethylene glycol, oils, and polymer solutions can be used as base fluids. In this chapter, we summarize the recent studies of using CNTs and graphene to improve the thermal conductivity of nanofluids. Moreover, we refer to the studies about the effect of using magnetic fields on enhancing the thermal conductivity of nanofluids. Too much discrepancy about thermal conductivity of nanofluids can be found in the literature. For carbon nanofluids, unfortunately, no significant improvements on thermal conductivity are observed using low concentrations. Different improvement percentages have been reported. This variation in the thermal conductivity can be attributed to many factors, such as particle size temperature, pH, or zeta potential. We believe that more research efforts need to be made in order to, first, improve the thermal conductivity of nanofluids and, second, assess the effect of the different parameters and conditions on the thermal conductivity of nanofluids.

“…The team further developed a facile technique to produce ethylene glycol based nanofluids containing GO nanosheets and the thermal conductivity enhancement ratios were up to 86% [24]. Ijam [28] prepared GO nanosheets /glycol-water-based nanofluids which kept stable for more than 5 months, the results showed that the improvement in thermal conductivity was up to11.7%. And then, hydrophilic graphene nanofluids have been explored for practical applications instead of traditional fluids, such as in solar collectors [29][30][31], miniature loop heat pipe [32][33][34][35] , and so on.…”

Enhancement of the heat transfer of the cold side is one of the approaches to improve the performance of thermoelectric generator systems (TEGs). In order to investigate viability and further performance of the TEG for waste heat recovery in industry area, a small low-temperature waste heat thermoelectric generator setup has been constructed with graphene oxide (GO) nanofluids as coolants in the paper. The results showed excellent stability of GO nanofluids through the preparation of two-step method to be applied in the TEGs .The highest open output voltage of TEG system were obtained by 0.15% weight fraction of GO nanofluids as coolant when the temperature difference (△T) was designed at 95K and the hot side temperature was fixed at 373K in the TEGs. Compared with conventional glycol-water base fluid as coolant, the highest open voltage enhancement ratio has reached 65.26% in the TEGs.
