“…Further, Graphene nanoplatelets nanoliquids thermal and hydrodynamic performance on integral fin heat sink ( Arshad and Ali [24]), pressure drop and heat transfer in a straight mini-channel heat sink using TiO2 nanofluid ( Arshad and Ali [25]), solar dish assisted S-CO2 Brayton cycle using nanoliquids flow (Khan et al [26]) and potential evaluation of ferric oxide and titania nanofluids (Babar and Ali [27] ) were carried out. Many other works have been conducted on natural convection within a variety of enclosures containing diverse types of inner bodies of various configurations implementing numerical computations/approaches such as finite volume, finite difference, and finite element method [28][29][30][31][32][33][34].…”

The purpose of the current study is to numerically investigate the effects of shape factors of nanoparticles on natural convection in a fluid saturated porous annulus developed between the elliptical cylinder and square enclosure. A numerical method called the control volume-based finite element method (CVFEM) is implemented for solving the governing equations. The modified flow and thermal structures and corresponding heat transfer features are investigated.Numerical outcomes reveal very good grid independency and excellent agreement with the existing studies. The obtained results convey that at a certain aspect ratio, increment of Rayleigh and Darcy numbers significantly augments the heat transfer and average Nusselt number. Further, enhancement of Rayleigh number increases the velocity of nanofluid while that of aspect ratio of the elliptical cylinder shows the opposite trend.

This study reveals the characteristics of chemical reaction on Marangoni mixed convective stream towards a penetrable Riga surface. The heat and mass phenomena are analysed within the sight of Dufour and Soret impacts. The administering partial differential equations system is converted into three nonlinear ordinary differential equations utilizing appropriately adjusted transformations. The resultant system of highly nonlinear equations is analytically solved by invoking the homotopy analysis method. Thereafter, the convergence of series solutions is discussed. The impact of appropriate parameters on various flow fields is thoroughly explained with the help of graphs and tables. The wall drag coefficient and relevant flux rates are arranged and discussed for dimensionless parameters. The outcomes show that the stronger Dufour effect of liquid causes a notable incremental variation in heat and mass flux, whereas an opposite trend is noted in the heat flux rate for the Soret effect. However, the mass flux is still found increasing for the stronger Soret effect.

“…eir results, which are expressed by isotherms, streamlines, velocity field, and average Nusselt numbers, show that the heat transfer for Fourier's law is improved as compared to the results obtained for the case of Cattaneo-Christov heat flux. e augmentation of heat transfer in most of these studies was attributed to the virtue of the abnormal enhancement of the nanofluid thermal conductivity [24][25][26].…”

This article consists of a numerical study of natural convection heat transfer in three-dimensional cavity filled with nanofluids. This configuration is heated by a partition maintained at a hot constant and uniform temperature TH. The right and left vertical walls are kept at a cold temperature TC while the rest is adiabatic. The fluid flow and heat transfer in the cavity are studied for different sets of the governing parameters, namely, the nanofluid type, the Rayleigh number Ra = 103, 104, 105, and 106, and the volume fraction Ф varying between Ф = 0 and 0.1. The obtained results show a positive effect of the volume fraction and the Rayleigh number on the heat transfer improvement. The analysis of the results related to the heat transfer shows that the copper-based nanofluid guarantees the best thermal transfer. In addition, the increase of the heating section size and Ra leads to an increased amount of heat. Similarly, increasing the volume fraction improves the intensification of the flow and increases the heat exchange.
