“…From the above review, the maximum enhancement of 190% in heat transfer as compared to de-ionized water was observed by Wang et al (2013) at 0.24 vol.%. For nonspherical nanoparticles, some other parameters including the aspect ratio, the dispersion state and aggregations of nanoparticles as well as shear field have significant impact on effective properties of nanofluid, convection heat transfer coefficient and pressure drop observed by Yu et al (2012). It is noticed by Yu et al (2013) that therminol 59 shows very attractive features for many commercial applications.…”

“…The experiment was performed by Anoop et al (2012) on forced convective heat transfer of nanofluids in a microchannel. The experimental results indicated that heat transfer increased with a flow rate for both water and nanofluid samples; however, for the nanofluid samples, heat transfer enhancements occurred at lower flow rates and heat transfer degradation occurred at higher flow rates (compared to that of water).…”

Nanofluids are suspension of nanoparticles (less than 100 nm) in the conventional base fluids. The dispersed solid metallic or non-metallic nanoparticles change the thermal properties like thermal conductivity, viscosity, specific heat, and density of the base fluid. Past studies focused on measuring the thermal properties of nanofluids. These suspended nanoparticles effectively improve the transport properties and heat transfer characteristics of the base fluids. Recently, heat transfer augmentation using suspensions of nanometre-sized solid particles in base liquids have been investigated by various research groups across the world. This paper reviews the state-of-the-art nanofluid studies in the area of forced convection heat transfer enhancement. The results for the heat transfer characteristics in internal flow with constant heat flux and constant wall temperature boundary conditions reported by various researchers have been compiled and reviewed. Further, in heat exchangers, the real boundary conditions are different from the constant heat flux and constant wall temperature boundary conditions. Over a span of 2 decades, the literature in this field is widespread; hence, this review would be useful for researchers to have a precise screening of a wide range of investigations in this area.

Two‐phase heat transfer is widely used in the heat transfer field, for example, condenser and evaporator in the refrigeration system, riser, and condenser in thermal power plants, and so on. The advantage of two‐phase heat transfer is that it gives a very‐high convective heat transfer coefficient compared to other modes of heat transfer. Nanofluid is a comparatively new heat transfer fluid and very popular because of its improved thermophysical properties. If nanofluid is used in a two‐phase heat transfer field, then the convective heat transfer coefficient may improve further. Nanofluids are possibly useful in many studies in two‐phase heat transfer like pool boiling heat transfer, flow boiling heat transfer, nanofluids in a microchannel, forced convective heat transfer, condensation, spray cooling, enhanced oil recovery, and so on. The effect of nanoparticles on wettability, contact angle, and nucleation sites are also reviewed in this paper. Numerical studies in two‐phase heat transfer are also reviewed and summarized in this paper. In this review, the chronological development of heat transfer in the two‐phase field is provided in a tabular form. This table covers a wide period starting Before Common Era ages until the recent addition of nanoparticles in the two‐phase heat transfer fluid.
