“…The study of non-Newtonian fluid fascinates researchers due to daily life significance in, and pastes, paints, biological fluids, motor oils, mechanical procedures, and complex mixtures. [20][21][22] Recently, many experts have been reported to analyze the dynamics of non-Newtonian fluids like tangent hyperbolic, 23,24 third grade, 25,26 Casson fluid, 27,28 power law nanofluid, 29,30 viscoelastic fluid, 31 and micropolar fluid. 32 The inherent difficulty in the solution of such problems due to the nonlinearity associated with convective terms in the formulation has been addressed by employing various numerical approaches such as finite difference (FD), finite volume (FV), boundary element (BE), and finite element (FE).…”

The Galerkin finite element approach is utilized to examine the significance of magnetic dipole and solar radiation on the dynamic of micropolar ferromagnetic fluid due to extending stretch surface. The magnetic field and the significant power of magnetic dipole help to stabilize the magnetized nanoparticles inside the fluid. The solid nano-sized particles are incorporated due to enhanced host fluid thermal conductivity, which plays a significant role in heat exchangers, modern nano-technology, electronics chips, and materials sciences. In the present elaborated problem, with the aid of similarity transformation, the partial differential formulation is transformed into a set of dimensionless ordinary differential equations, and finds a numerical solution via finite element discretization. The detailed parametric study corresponding to various physical conditions is carried out to reveal that incremented ferromagnetic interaction variable recedes the flow speed, but it grows the thermal and microrotation distributions, and the decline in temperature is observed with the increment of ratio, viscous dissipation, and curie temperature parameters.

“…Moreover, the study of fluid flow through porous medium has been a topic of great interest to many researchers. [13][14][15][16][17][18] Various research studies, in recent times, focus on particular scenarios when the thermal boundary conditions allow the governing equations to be reduced to a set of ordinary differential equations (ODEs) using similarity transformation and generally this happens due to plane heated surface. However, surfaces are often purposefully roughened because it has a significant impact on reducing drag force while it is also used to improve the heat transfer rate.…”

The influence of complex roughened surface on the Darcy-Forchheimer natural convection flow is investigated numerically. A natural convection flow within porous medium occurs in a variety of engineering applications that include solar power collectors that are used to control the pollutant spread, cooling of nuclear reactors, and geothermal engineering. Recent research has focused on reducing skin friction drag induced by viscous forces acting on a rigid body surface as it moves through a fluid by considering roughened surface or mass transfer (mass injection or suction) at the surface. The purpose of this study is to investigate how much skin friction drag reduces by considering complex roughened surface in Darcy-Forchheimer natural convection flow. A mathematical model is obtained in the form of nonlinear PDEs by transferring surface roughness effect from boundary to governing equations and made dimensionless through suitable scaling variables. To obtain a numerical solution for resulting nonlinear PDEs, a finite difference scheme is applied. The results reveal that skin friction drag reduces by making roughened surface a complex surface and further reduces by adding the combined effects of Darcy and Forchheimer numbers also total heat transfer rate enhances by increasing the values of Darcy as well as Forchheimer numbers. These results seem novel findings in this study.

A numerical study is performed to discuss the heat and mass transfer on oblique stagnation point flow over a lubricated surface with nonlinear thermal radiation and higher-order chemical reactions. The problem is formulated using basic conservation laws of mass, momentum, energy, and mass concentration in terms of partial differential equations along with nonlinear boundary conditions. These governing equations are transformed into ordinary differential equations by means of similarity transformations. The system of resulting ordinary differential equations are solved numerically by an implicit finite difference scheme known as the Keller-box method. The quantities elaborated in the problem, such as velocity, temperature, skin friction, and local Nusselt and Sherwood numbers are analyzed for several values of involved parameters. The obtained results are presented through various graphs and tabular data and showed a good agreement with the existing results in the literature, which are the subcases of the present work. The heat transfer rate enhances with nonlinear thermal radiation and mass transfer rate decreases with increasing the order of chemical reaction.
