Investigation on Rotating Flow of Magnetohydrodynamic Tangent Hyperbolic Nanofluid Over a Stretching Permeable Sheet: Impacts of Hall, Ion Slip and Suction Velocity

Abstract

This study explores how suction factor, Hall current, ion slip, and rotation influence flow of magnetohydrodynamic (MHD) tangent hyperbolic nanofluid over a stretching permeable sheet, incorporating the effects of non-Newtonian parameters, joule heating, viscous dissipation, nonlinear thermal radiation, heat generation/absorption, and chemical reactions. The nonlinear differential equations of the problem, converted by similarity transformations and non-dimensional variables, were solved numerically with the sixth-order Runge-Kutta method alongside the shooting approach. The analysis examined the impact of various physical parameters on velocity, temperature, and nanoparticle concentration profiles, using graphical representations to highlight the significance of each parameter. Additionally, the study assessed the influence of various physical parameters on the surface drag force coefficients as well as heat and mass transfer, supported by numerical values. The findings revealed that the surface drag force coefficient in the x direction decreased with higher Hall current and ion slip parameter values, whereas an opposing effect was noted with increment of suction factor and rotation parameter. In contrast to mass transfer, heat transfer was positively affected by the suction factor, Hall, and ion slip parameter. We validated our method against existing literature, and our numerical results showed excellent agreement, confirming its accuracy and robustness.
