Effects of inclined Lorentz forces on boundary layer flow of Sisko fluid over a radially stretching sheet with radiative heat transfer

Abstract

The inclined magnetic field effect on the boundary layer flow of Sisko fluid model over a radially stretching sheet is investigated. The effects of viscous dissipation and thermal radiations are also taken into account. It is assumed that the magnetic field is applied with an inclined angle γ which varies from 0 • to 90 •. The suitable transformations are used to convert the governing partial differential equations into a set of non-linear coupled ordinary differential equations. The numerical solution of the governing problem is obtained by using fourth-order Runge-Kutta method with shooting technique. The obtained results for velocity and temperature are expressed through graphs against various emerging physical parameters such as magnetic parameter, angle of inclination, Prandtl number, radiation number, Eckert number and material parameter of the Sisko fluid for different values of power law index. It is found that increasing value of aligned angle strengthens the magnetic field and decreases the velocity profile and enhances the heat transfer rate. Further, the numerical values are given in tabular form for the local skin friction coefficient and the local Nusselt number.

Numerical Analysis of Natural Convection Driven Flow of a Non-Newtonian Power-Law Fluid in a Trapezoidal Enclosure with a U-Shaped Constructal

“…Ouertatani et al [26] numerically assessed Rayleigh-Benard convection within a rectangular domain and yielded uniformness in streamlines and isothermal patterns for the magnitude of the Rayleigh number approaching 100. Some recent development in this direction are addressed and accessed in [27][28][29][30][31][32][33][34][35][36][37][38]. Usman et al [39] studied the transportation of heat within a power-law liquid in the presence of a sinusoidal heat sink/source between stretchable disks separated with a constant gap and rotating co-axially.…”

“…Goodarzi et al [44] measured the convective heat transportation in a shallower chamber by incorporating two phasic nano models. Goodarzi et al [33][34][35][36][37][38] jointly executed comparative analysis regarding accurate findings for heat flux calculation by utilizing different numerical techniques. A numerical analysis of MHD natural convective fluid flow enclosed between two h-distance apart plates was studied by Rasool et al [39] Safaei et al [40] numerically deliberated free convective heat transfer fluid flow inside an elliptical container with varied attack angles.…”

The effect of energy accumulation and boundary slip on laminar flow between rotating plates

“…On the other hand, the excessively reduced fluid viscosity due to the elevated temperature resulting from power consumption during prolonged operation is not conducive to the generation of dynamic pressure. 3 In addition, ensuring the service life of the sealing parts under high-temperature conditions during prolonged operation times is difficult. 4 The phenomenon of boundary slip has long been widely studied, as reported in Refs.…”

“…When the friction pair attains complete fluid lubrication, the energy due to the resistance between the wall and liquid is essentially converted into the internal energy of the fluid, causing the temperature to increase. 3 Nevertheless, the internal energy of the fluid can be modified due to the effective decrease of the wall resistance by the drag reduction of the boundary slip. 19 In this study, we chose to examine the flow between rotating plates and to model the mechanisms of the resistance changes and explain how the boundary slip maintains good temperature control during long-term operation of the rotating plates.…”

“…Mahmood et al [12] elaborated the electrically conducting viscous fluid through porous medium. Impact of inclined Lorentz forces on Sisko fluid flow is numerically analyzed by Ahmed et al [13]. In the above-mentioned studies, the researchers restricted their flow and heat analysis only for non-Newtonian Maxwell liquid.…”
