“…Hamed et al [13] prepared nanofluids to optimize energy consumption using models. Nirupama Patra et al [14] investigated the quenching characteristics of metallic vertical rod of stainless steel (SS316L) with an internal heater in alumina-water base nanofluid at different operating Sarafraz et al [20] suspended CuO nanoparticles into water (base fluid) and demonstrated an experiment to evaluate the thermal performance of a cooling loop working with liquid gallium and CuO/water nanofluid. Results showed that CuO/water nanofluid presents lower pumping power and can be a better alternative for cooling systems compared to the liquid gallium, Ghasemi et al [19,21] investigated the influence of geometry of channel on the thermal performance of a mini-channel CPU cooler and showed that, with an increase in diameter of channel, pressure drop in the heat sink reduces.…”

Nanofluid has become popular with the advancement in nanotechnology. Nanofluid has comparatively better stability than the microfluid because here much smaller‐sized particles (nanometer size) are suspended in the base fluid. It has improved thermophysical properties and convective heat transfer coefficient than the base fluid alone. That is why researchers have implemented this novel heat transfer fluid in versatile fields. These are solar collectors, solar thermal energy storage, electronics cooling, cooling and heating, heat pipes, automobile radiator, refrigeration system, natural convection, quenching, and many other applications. These varied applications indicate that in imminent future nanofluid will play a major role in these fields. Though all these trials are at present at academic research level, however, with the advancement in nanotechnology, surface science, colloidal chemistry, and so forth this nanofluid will definitely play a major role in heat transfer in the coming days.

“…Compared to some reported values of CHF enhancement [18], the CHF enhancement of the nanofluids in this study is comparable and large enough. Fluid with large CHF was required for some applications such as RVCS and ECCS in Nuclear Reactor [19], metal machining [20], and quenching [21,22]. Benefit of the application of nanofluids in metal machining [Shokohii 20] covering drilling, turning, milling, and drilling was reported in a literature [20].…”

In order to develop a new coolant for nuclear and non-nuclear applications, nanoparticles of Al2O3 for nanofluids have been successfully synthesized by solgel method utilizing AlCl3 as precursor and urea as chelating agent. The mole ratio of the AlCl3 and urea was 1:2. The solution was stirred to form a sol and then was heated at 150 o C until forming a gel. The gel was then calcined at 500 o C for 1 hour to get Al2O3 nanoparticles. Nanofluids of Al2O3 were prepared by dispersing the Al2O3 nanoparticles into water as base fluid. The synthesized Al2O3 nanoparticles crystallized in gamma phase with crystallite size of 3.4 nm as confirmed by the XRD analyses. Specific surface area of the nanoparticles was 251 m 2 /g with dBET of 6 nm. As confirmed by TEM analyses, the particle size of the nanoparticles was 35 nm. The nanofluid with concentration of 0.05 vol % and pH of 7.42 possessed zeta potential of 53 mV, indicating a stable suspension. This nanofluid had a CHF enhancement of 92% compared to water as base fluid.
