The intent of this investigation is to analyze the Williamson nanofluid stream past a nonlinearly broadening surface through a leaky medium in the existence of mixed convection, Hall, ion‐slip, thermal radiation, and viscous dissipation impacts. Suitable similitude changes give joined nonlinear differential schemes, which were numerically explained via spectral relaxation method. Effectiveness of various physical parameters on velocity ingredients, temperature, and nanoparticle concentration distributions alongside the physical quantities of interests was uncovered graphically. It is found that both velocity profiles increment with an expansion in the Hall parameter. Also, the opposite behavior is noticed for the primary and auxiliary velocity profiles as the ion‐slip parameter rises. Moreover, it is observed that the primary velocity and concentration profiles expand with an expansion in the velocity power index parameter, however, the secondary velocity profile reduces. Further, it was showed that the fluid velocities decay while temperature distribution advances by the superior values of the Williamson fluid parameter. Finally, the authenticity of the outcomes was confirmed by contrasting them with prior outcomes under some limited presumptions and discovered to be in terrific understanding.

“…Moreover, some studies on the magnetohydrodynamic flow of partially ionized liquid adopting stated laws 32 have been discussed. Nasrin et al 33 studied the incompressible 2D partially ionized fluid flow in the existence of a transverse magnetic field along with a rotating semi-infinite vertical plate with a porous medium by utilizing the perturbation scheme. Takhar et al 34 studied the Hall current impact under the influence of the magnetic field amalgamated with free stream velocity in a non-similar flow past a moving surface.…”

Nanofluids play a pivotal role in the heat transport phenomenon and are essential in the cooling process of small gadgets like computer microchips and other related applications in microfluidics. Having such amazing applications of nanofluids, we intend to present a theoretical analysis of the thermally stratified 3D flow of nanofluid containing nano solid particles (Cu and Al2O3) over a nonlinear stretchable sheet with Ion and Hall slip effects. Moreover, the features of buoyance effect and non-uniform heat source/skin are also analyzed. For the study of numerically better results, Tawari and Das model is adopted here. For the conversion of the system of partial differential equations into ordinary differential equations, apposite transformations are engaged and are tackled by utilizing the bvp4c scheme of MATLAB software. The effects of dimensionless parameters on velocity and temperature profiles are depicted with the help of graphs. Additionally, the Skin friction coefficient and Nusselt number for the practical applications are examined in the tabular form. Verification of the current study by comparing it with an already published work in a special case is also a part of this study. Results show that the thermal performance of copper nanoparticles is more than alumina nanoparticles. An upsurge in the temperature of nanofluid is observed when the strength of the magnetic field is enhanced. However, the temperature of partially ionized nanofluid is significantly lowered because of the collisions of electrons and ions.

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.
