“…In recent years, the investigation of Hall current effect on MHD flows has been given more importance because in many industrial and practical applications, applied magnetic field is very strong or fluid is highly ionized. In light of these, Seth and Singh, 36 Singh et al, 39 Chamkha et al, 42 Seth et al, 43,44 Pandit et al, 45 Reddy et al, 46 Hussain et al, 47 Sarkar and Seth, 48 Makinde et al, 49 Shamshuddin et al, 50 and Sreevani 51 presented the consequences of Hall current on MHD flows by considering various facts and geometries.…”

In this paper, the steady magnetohydrodynamic mixed convection flow of a viscoelastic fluid over a magnetized vertical surface embedded in a uniform porous material with rotation is considered. The Hall and induced magnetic field effects are also considered in this investigation. The regular perturbation technique is used to find the solutions of flow governing equations. To analyze the consequences of flow-influencing parameters to the flow variables, numerical computation has been performed and the results are illustrated in graphical and tabular forms. It is interesting to note that magnetic diffusion leads to the increase of the fluid flow. It brings a decrement in the induced magnetic field in the vicinity of the magnetized vertical surface.

“…Sometimes the ion-slip phenomenon is ignored from the investigation because the diffusion velocity of ions is lesser than the electrons. The aforesaid facts and applications motivated the authors [33][34][35][36][37][38][39][40][41][42][43][44][45] to examine the Hall phenomenon on buoyancy-driven MHD boundary layer flows. The simultaneous impacts of magnetic diffusion and Hall effects are reported in the research articles of Seth and Singh, 17 Singh et al, 25,28 and Kumar et al 21,29 During the heat and mass transportation process, the heat transfer can neither be set up only by temperature drop but it can be also set up due to concentration drop.…”

The key objective in this study is to examine the heat and mass transport behavior of magnetohydrodynamic elastic-viscous fluid flow over a vertically oriented magnetized surface placed in a uniform permeable regime with magnetic and thermo diffusions. The fluid is partially ionized and permeated to flow in the presence of a strong magnetic field domain. Hence the Hall current effect is considered in this investigation. The significance of rotation and induced magnetic field on the flowing nature are also scrutinized in this study. The mathematical model of the problem is converted to a similar model by introducing suitable nondimensional variables. To obtain the closedform solutions of the flow leading equations, the regular perturbation analysis is utilized. For the exhibition of results, figures and tables are generated with the assistance of scientific computation software MATHEMATICA. Computed results are validated with the existing result in the limiting case. Such an investigation is important in evaluating the flow characteristics of low magnetic diffusive viscoelastic fluid. A noteworthy result seen is that magnetic diffusion significantly controls the

In this mathematical presentation, we examined the significance of Hall current on MHD buoyancy‐driven boundary layer flow of a Ti6Al4V‐H2O based nanofluid past a vertical surface implanted in a uniform permeable region. The vertical surface is considered to be magnetized and induced magnetic field (IMF) impacts are also considered. The nondimensional flow model is solved with the assistance of the two‐term perturbation scheme. Various results are obtained by numerical computation for different significant parameters. These results are presented and analyzed in graphical and tabular form. In the boundary layer domain, the transpiration velocity across the surface tends to diminish the main flow, IMF along the main flow, fluid temperature, and concentration. It is remarkably noted that IMF along the main flow grows for incrementing values of volume fraction coefficient of nanofluid. In the magnetic boundary layer domain, the main flow and IMF along the main flow grow with Hall current. Furthermore, it is seen that for the progressing values of magnetic Prandtl number, the main flow reduces while normal flow and IMF along the main flow is induced in the boundary layer domain.
