This manuscript reviews most of the available papers on the nanofluids convection in different shapes of cavities and enclosures, applying a magnetic field. The papers have been categorized into two major classes: natural convection and mixed convection. Important research have been described more and then two tables demonstrate a summary of the papers. Statistical considerations are mentioned to realize some helpful information on the scope. Most of the results demonstrated that the heat transfer usually enhances with an increase in nanoparticles volume concentration and Rayleigh number and shows inverse behavior with growth in the Hartmann number. The average Nusselt number will decrease with any increase in the Richardson number.Moreover, magnetohydrodynamic constraints the heat transfer and therefore, can play as an applicable controller of heat transfer applications.

“…In a similar manner, many researchers have conducted their research on flow and heat transfer analysis in different channels in different aspects of the physical model. [34][35][36][37][38][39][40][41] From the above-mentioned literature survey, in the present study, we intend to study the impact of Hall on couple stress fluid flow through a vertical microchannel under the aspects of radiative heat flux, viscous dissipation, Joule heating, heat generation, and magnetism. The numerical investigations on fluid velocity, thermal field, reversibility, and irreversibility ratio are performed.…”

The present study analyzes the irreversibility in an electrically conducting couple stress fluid between two vertical channel plates with the aspects of exponential space and temperature-dependent, radiative heat flux, heat generation, and Joule heating. A reduced system of the governing equations is obtained via applying suitable nondimensional variables. To determine the solutions of velocity, thermal field, irreversibility, and irreversibility ratio, the Runge-Kutta-Fehlberg method along with the shooting technique has been employed. The various pertinent parameters that are involved in the problem have been discussed in detail through graphs. The results show that the entropy production can improve with the viscous dissipation, Joule heating, exponential space and temperature-dependent, and radiative heat flux. Furthermore, it is clear that the entropy enhances with wall ambient temperature difference, radiation parameter, and the effect is reversed with higher estimations of the fluid wall interaction parameter, couple stress parameter, and rarefaction. The present numerical results are compared with the existing results that are in good agreement.

“…In fact, Buongiorno's model states that there are thermo-diffusion and diffusion-thermo effects in nanofluids and hence an anomalous convective heat transfer is reported. Buongiorno's model plays an incredible role for various researches on different aspects of nanofluids [5,[8][9][10][11][12][13][14][15].…”

Triple diffusive convection with Soret–Dufour effects in a Maxwell nanofluid saturated in a Darcy porous medium

Soret-Dufour phenomenon in a Darcy-Maxwell Brownian nanofluid is performed using a macroscopic filtration model, suggested by Alishayev (Hydromechanics 3:166-174, 1974). For nanoparticle flux at the boundaries passive management, influenced by the management of concentration flux assumed in Stefan's flow, is considered. Normal mode technique is used to analyse the stationary and oscillatory convections under the linear stability theory. The effects of different phenomenon are quantified by dimensionless parameters. It is found that the Soret parameter has dual behaviour for stationary convection and destabilizing behaviour for oscillatory convection, whereas the Dufour parameter has a stabilizing effect for both stationary and oscillatory convections. Nonlinear stability analysis provides the behaviour of flux of heat, salt and nanoparticles in the flow field through Nu , Nu C and Nu . Steady and unsteady convections are discussed. A graphical representation of streamlines, isotherms, isohalines and flow lines of nanoparticles concentrations is presented.Keywords Darcy-Maxwell nanofluid · Soret-Dufour-driven convection · Linear and nonlinear instability · Passive management of nanoparticle at the boundaries
