“…The study showed that the 2D problem can provide a reasonably accurate prediction of heat transfer rate at low Rayleigh numbers. Pasha et al [ 33 ] focused on modeling and numerically simulating the characteristics of entropy production and spontaneous convective flow, in a hexagonally shaped region subjected to an angled magnetic field. The area with a non-Newtonian fluid inside that thickens under shear and is charged with Alumina nanoparticles.…”

“…Furthermore, Rayankula and Ganganapalli [13] used a numerical scheme to research the micropolar liquid with the temperature‐dependent heat generation/absorption along a nonlinear extending plate under the influence of convective boundary constraint. Recent investigations have emphasized examining the upshots of an inclined magnetic field on various flows of nanofluids, as discussed in scholarly works referenced [14–17].…”

Amongst numerous non‐Newtonian fluid models, Eyring‐Powell fluid is prominent owing to its shear thinning, pseudoplastic, and yield stress unique characteristics. It has varied industrial applications including the modeling of polymer melts, food products, and blood flow. This study discusses the Darcy Forchheimer flow of Eyring‐Powell nanoliquid along a nonlinear stretched surface influenced by an inclined magnetic flux. The mass and heat transmissions are supported by active and passive control of nanoparticles respectively. The unique effect of viscous dissipation is introduced to influence the liquid velocity and temperature. Unlike the majority of the research being published that espouses similar solutions, we adopted the non‐similar analysis of the proposed problem to eradicate the chance of the variable in the parameters. This was a challenging task and was taken as a mathematical art rather than a science. The established Buongiorno model is followed to compute the thermophoretic and Brownian motion effects. The numerical computation of this mathematical system is performed using the bvp4c algorithm. The results are described through graphs and in numerically calculated tabulated values. It is determined that wall drag is stronger when the magnetic field is inclined at an angle of than at . Additionally, it is observed that passive control of nanoparticles results in better rates of heat and mass transmissions, against varied values of the fluid parameter with . The validation of the envisioned model is also a part of this exploration.

“…Natural convection heat transfer in a porous prismatic enclosure with two movable hot baffles was examined by Shao et al 25 . Pasha et al 26 studied heat exchange, natural convective flow, and entropy-generating features in a hexagonal-shaped region controlled by an inclined magnetic field and filled with a non-Newtonian shear-thickening fluid charged with Alumina nanoparticles. Mondal et al 27 created CuO–H2O nanofluids in a 2D circular geometry with a rhombus-shaped barrier that keeps two neighbouring high walls at the same temperature.…”

Heat transport in a 2D steady radiative boundary layer with Maxwell fluid flow and the influence of heat generation and MHD has been studied across a porous inclined vertical plate. Through similarity transformation, the mathematical modelling is converted to ODEs, and the built-in solver Bvp4c via MATLAB is used to solve. The linear movement of an inclined porous plate introduced the flow. The MHD (M), Prandtl number (Pr), radiation (Rd), Rayleigh number (Ra), local Nusselt number (Nux), angle of inclination (γ), and material relaxation time (β) have a considerable impact on the flow field as a result. The local Nusselt numbers and the skin friction coefficient are also given as numbers. The validation with the numerical solution is presented. The results are shown, and a thorough physical analysis has been done. The temperature of the fluid rises due to the greater electric field, increasing the heat transfer on the inclined plate. However, skin friction increases dramatically as the heat radiation parameter rises. The critical findings of this study are that the temperature profile increases and the velocity profile lower as the inclination angle increases. The Maxwell fluid parameter raises the velocity profile as well.
