“…The forced and natural convective heat transfer behaviours of nanofluids in various mediums have been studied. Such studies as the heat transfer behaviour of nanofluids in cavities [309][310][311][312][313], porous materials [314][315][316] and jet impinging [317] all show an increase in the dimensionless heat transfer parameter with the addition of nanoparticles. These studies prove the tremendous potentials of nanofluids in the electronics and data storage industries.…”

The field of nanofluids has received interesting attention since the concept of dispersing nanoscaled particles into a fluid was first introduced in the later part of the twentieth century. This is evident from the increased number of studies related to nanofluids published annually. The increasing attention on nanofluids is primarily due to their enhanced thermophysical properties and their ability to be incorporated into a wide range of thermal applications ranging from enhancing the effectiveness of heat exchangers used in industries to solar energy harvesting for renewable energy production. Owing to the increasing number of studies relating to nanofluids, there is a need for a holistic review of the progress and steps taken in 2019 concerning their application in heat transfer devices. This review takes a retrospective look at the year 2019 by reviewing the progress made in the area of nanofluids preparation and the applications of nanofluids in various heat transfer devices such as solar collectors, heat exchangers, refrigeration systems, radiators, thermal storage systems and electronic cooling. This review aims to update readers on recent progress while also highlighting the challenges and future of nanofluids as the next-generation heat transfer fluids. Finally, a conclusion on the merits and demerits of nanofluids is presented along with recommendations for future studies that would mobilise the rapid commercialisation of nanofluids.

“…Very recently, Chamkha et al [16] studied MHD convective heat transfer of Cu-water nanofluid saturated porous medium considering heat generation/absorption. Convective heat transfer in cavities has also been studied by Bondarenko et al [17] considering two adherent porous blocks in a lid-driven cavity and Maghsoudi and Siavashi [18] considering a twosided lid-driven porous cavity. Akar et al [19] have analyzed turbulent fluid flow around a rotating cylinder and evaluated entropy generation.…”

MHD convection in a partially driven cavity with corner heating

The paper presents a pertinent modification to the wall-moving thermal systems (classically represented by lid-driven cavity) by introducing a partial motion of the boundary walls. The effect of partial wall motion is investigated under magnetohydrodynamic (MHD) mixed convection in the cavity filled with porous medium. The corner heating arrangement is chosen for this investigation. The heater is placed at the right-bottom corner of the cavity, whereas the halves of the adjacent sides (which are moving) of the top-left corner are utilized for cooling. The present MHD thermofluid flow in porous cavity under partially driven condition is solved numerically using Brinkman-Forchheimer-Darcy model and analyzed using heatlines, streamlines, isotherms and average Nusselt number. The detailed insights of partially driven cavity are captured for different values of Richardson number (Ri = 0.1-100), Reynolds number (Re = 10-500), Hartmann number (Ha = 0-100), Darcy number (Da = 10 −7 to 10 −3) and porosity (ε = 0.1-1.0). The result reveals that the partial wall motion and its direction have a significant impact on the thermofluid flow structures and heat transfer rate.

“…They found that fluid circulation was much more affected by increasing supplied voltage reflects than the increase in the Darcy number. Bondarenko et al 16 analyzed the impact of the two-centered porous block on heat transfer of Al 2 O 3 -water nanofluid flow in a cavity. They reported that by expanding porous block size, the heat conduction effects were increased and cooling was not performed efficiently in the enclosure.…”

Mixed convection of nanofluid in a 2D square enclosure with a porous block in its center and four rotating cylinders, which are forced by a simple harmonic function, was studied numerically. The porous zone was studied by considering the Forchheimer–Brinkman-extended Darcy model. Effects of various parameters including Darcy number (10–5 ≤ Da ≤ 10–2), porosity (0.2 ≤ ɛ ≤ 0.7), Richardson number (0.1 ≤ Ri ≤ 10), and volume fraction of nanoparticles (0 ≤ ϕ ≤ 0.03), on heat transfer, entropy generation, PEC, velocity, streamline and isotherm contours were demonstrated. The results show that decreasing the Darcy number as well as reducing the Richardson number leads to an increase in the average Nusselt number. However, porosity changes had no decisive effect on heat transfer. Maximize the volume fraction of copper nanoparticles in the base fluid enhanced heat transfer. In the case of the high permeability of the porous medium, the impact of the harmonic rotation of the cylinders on the flow patterns became more pronounced.
