“…Minakov et al [16] carried out experimental study of forced turbulent convection of water-based nanofluids with nanoparticles of zirconium oxide (ZrO2) in smooth tubes and channels with wall heat transfer enhancers. Nanopowders with average particle size of 44 and 105 nm were used in the experiments.…”

This paper presents a detailed review of the numerical studies carried out by various researchers in order to obtain enhanced heat transfer in free, forced, and mixed convection, under laminar, transition, and turbulent flow regimes, by using nanofluids in different solar collector geometries. Recently, nanofluids have been increasingly used in various solar collector configurations. Nano-sized metallic or non-metallic particles such as Cu, Au, Al2O3, SiO2, TiO2, CuO, etc, were used in the heat transfer fluid for various solid volume fractions. The average size of the particles was less than 100 nm. The higher conductivity of nanoparticles even at low particle concentration results in higher thermal conductivity of the base fluid and improves the thermal characteristics of the system. Nanoparticle size, type and shape are important factors for the thermal conductivity enhancement of the nanofluid with nanoparticles.

“…Minakov et al 126 have calculated the hydrodynamic length (

l_{h}

) for stabilization in the tube using Equation (33). They have concluded that for 44 nm‐sized ZrO 2 ‐water nanofluids, the HT enhancement ( h ) is increased by 35% and for 105 nm‐sized ZrO 2 ‐water nanofluids, the HT enhancement ( h ) is decreased by 20% compared to pure water at a fixed Re number.…”

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.

“…Similar observation also was found by Zainal Abidin et al [87] and Abdullah et al [3] however for different types of nanofluids. Furthermore, Minakov et al [88] evaluated the heat transfer performance of ZrO2/water nanofluids for 4.0% volume concentrations with different nanoparticle sizes of 44 and 105 nm. The experiment was undertaken for Reynolds number of 3,000 to 8,000 and different types of tubes viz.…”

Nanofluids have been widely explored by various investigators for different types of nanomaterials either the single nanoparticles or hybrid types. This is due to their advantages in thermal properties as well as contribution to the enhancement in the heat transfer performance. Numerous numbers of studies were performed mostly on oxide nanofluids until today. However, the review on oxide nanofluids and their applications is limited. Hence, this paper highlights the most recent development solely on the oxide nanofluids for heat transfer applications. In addition, a comprehensive review is carried out on the recent studies of thermo‑physical properties on oxide nanofluids and their heat transfer applications. The numerical and experimental studies related to forced convection heat transfer using oxide nanofluids were presented. Most of the literatures confirmed the capability of nanofluids to improve the heat transfer performance and simultaneously insignificant increments in pressure drop. Hence, the oxide nanofluids is recommended for applications in various engineering systems.
