“…This came about as a result of their discussion regarding increasing the Hall current parameter estimate on both carbon nanotube velocity profiles. According to Rani et al (2020), they studied the Hall and Iron slip on MHD nanofluid effect on flow over a vertical semiinfinite plate embedded in a porous media. They concluded that an unsteady perimeter has little effect on Casson nanofluid velocity distribution.…”

Fluid flow through this media is a key component in a wide range of activities like the generation of fluids from subsurface reservoirs and subterranean water resource restoration. Consequently, the study’s goal is to investigate the motion of Magneto Hydro Dynamics (MHD) nanofluids across a convectively heated plate superimposed on a radially expanding sheet embedded in a porous media. The model is formulated and non dimensionalized using similarity variables. By employing the shooting technique to transform the boundary conditions and, the R-K scheme in MATLAB bvp4c, the system of ODEs is solved. The results obtained are displayed in graphs and others in tables. The results indicate that with increasing porosity, magnetism, and surface rotation, the flow primary velocity decreases while the temperature profile surges. The findings from this study will provide beneficial theoretical insight into what parameters should be varied for maximum profit in several sectors like the power engineering sector, aerodynamic combination, drug recovery systems, and water solar heating systems.

“…Other most recent investigations on Hall and ion-slip impacts are given in References. [32][33][34][35][36][37][38][39][40] As far as we know, the mixed convection flow of Maxwell nanofluid past an extending sheet with Hall and ion-slip impacts has not been thoroughly considered at this point. Along these lines, the goal of the present investigation is to study the Hall and ion-slip effects on mixed convection flow of a Maxwell nanofluid over a permeable extending sheet employing the spectral relaxation method (SRM).…”

This article investigates the Hall and ion‐slip impacts on the mixed convection flow of a Maxwell nanofluid over an expanding surface in a permeable medium. The impacts of Brownian movement and thermophoresis parameters, Soret, Dufour, viscous dissipation, chemical reaction, and suction parameters, are, moreover, considered. Using the similitude changes, the partial differential equations with regard to the momentum, energy, and concentration equations are transformed to an arrangement of nonlinear ordinary differential equations, which are handled numerically utilizing a spectral relaxation method (SRM). The impacts of noteworthy physical parameters on the velocities, thermal, and concentration distributions are investigated graphically. Moreover, the numerical values of skin‐friction coefficients, local Nusselt number, and Sherwood number for different values of the mixed convection parameter ( γ ) , Deborah number ( λ ) , Hall parameter false( β H false) , ion‐slip parameter false( β i false) , Dufour number (Du), and Soret number ( Sr ) are computed and tabulated. It is discovered that ascent in Deborah number reduces both the stream and transverse velocity profiles, while the inverse pattern is seen with augmentation in the mixed convection parameter. In addition, inverse patterns of the stream and transverse velocity profiles are seen with expansion in magnetic, Hall, and ion‐slip parameters. Besides this, the temperature and concentration disseminations decline with augmentation in Dufour number and chemical reaction parameters, respectively. It is likewise seen that both the skin‐friction coefficients lessen with expansion in Deborah number, and they ascend with upgrade in blended convection and ion‐slip parameters, while the opposite condition is noticed with augmentation in Hall parameter. Furthermore, the reverse trends of local Nusselt and Sherwood numbers are discovered with expansion in the Dufour and Soret numbers.

“…In this view, the Hall effect occurred as a result of the Lorentz force's action. In the case of a conductor, a current is passed and a magnetic field is applied perpendicularly Dharmaiah et al (2020). As a result, the electrical field potential of the system is developed in both directions of the current and the magnetic field.…”

This methodology presented the unsteady three-dimensional laminar flow since Hall effects inducing the cross flow in z-axis. The boundary layer and the low magnetic Reynolds number approximations are used to simplify the system of equations derived from the constitutive laws. The upper-convected Maxwell (UCM) fluid model used for Hall effects with unsteady heat transfer, which passed through the infinite stretching sheet. This flow model has intensified with the effects of magnetohydrodynamic (MHD), thermal radiation and heat generation-absorption. Here, we selected the two-parameter Lie scaling transformations to convert the highly non-linear partial differential equations (PDEs) to the ordinary differential equations (ODEs) which are studied numerically using the MATLAB bvp4c method. The main parameters are: Deborah number Deu, Hartmann number Mu, Hall effects parameter mu, Prandtl number P r, thermal radiation parameter δu and heat generation-absorption Qu. Hall effects reduced the transport rate in the x-axis but increased the transport rate in the z-axis. On the other hand, the Hall parameter is extravagant to transport the internal energy of the system.
