TL;DR: A review of the most recent studies on nanofluid in the literatures is presented in this article, where the authors take into account the contributions of different researchers available in open literature on different aspects of Nanofluids such as thermal conductivity, viscosity, experimental, numerical studies on heat transfer performances and applications.
Abstract: Nanofluids are attracting many researchers for their superior thermo-physical properties with no or low penalty in pressure drop. The review is made by considering different parameters which govern the nanofluids characteristics, heat transfer performance and its application. Maximum effort is taken to account the contributions of different researchers available in open literature on different aspects of nanofluids such as thermal conductivity, viscosity, experimental, numerical studies on heat transfer performances and applications of nanofluids. The intention of this review is to provide an overview of the most recent studies on nanofluid in the literatures. It will be very useful for the scientific community working on nanofluid to update their knowhow about the nanofluid.

TL;DR: In this article, the authors examined the effects of Al2O3/water hybrid nanofluid on the mixed convection inside a square cavity caused by a hot oscillating cylinder and found that the motion of the cylinder toward the top and bottom walls increases the average Nusselt number when the Rayleigh number is low.
Abstract: The aim of this paper is to examine the effects of Cu–Al2O3/water hybrid nanofluid and Al2O3/water nanofluid on the mixed convection inside a square cavity caused by a hot oscillating cylinder. The governing equations are first transformed into dimensionless form and then discretized over a non-uniform unstructured moving grid with triangular elements. The effects of several parameters, such as the nanoparticle volume fraction, the Rayleigh number, the amplitude of the oscillation, and the period of the oscillation of the cylinder are investigated numerically. The results indicate that the motion of the oscillating cylinder toward the top and bottom walls increases the average Nusselt number when the Rayleigh number is low. Furthermore, the presence of Al2O3 and Cu–Al2O3 nanoparticles leads to an increase in the values of the average Nusselt number Nuavg for cases of low values of the Rayleigh number. It is found that the natural convection heat transfer rate of a simple Al2O3/water nanofluid is better than that of Cu–Al2O3/water hybrid nanofluid.
