Hall and ion slip effects on magnetohydrodynamic convective rotating flow of Jeffreys fluid over an impulsively moving vertical plate embedded in a saturated porous medium with Ramped wall temperature

Abstract

In the present study, it is explored theoretically Hall and ion slip effects on the unsteady magnetohydrodynamic (MHD) rotating flow of a viscous, incompressible electrically conducting, and optically thick radiating Jeffreys fluid over an impulsively, moving vertical plate embedded in a saturated porous medium, when the temperature of the plate has a provisionally ramped profile. The exact solutions of the governing equations for the flow domain are attained by making use of the Laplace transform method. The specified analytical solutions are also acquired for some limiting cases. The research phrases of engineering curiosity for skin friction and Nusselt number are originated for both ramped wall temperature and the isothermal plate. Sherwood number is also obtained. The numerical results of velocity, temperature, and concentration distributions are exhibited graphically whereas skin friction, Nusselt number, and also Sherwood number are mentioned in a table form. It is observed that on either cases of ramped wall temperature and isothermal plate, the resultant velocity enhances with an increase in Hall and ion slip parameters. Reversal behavior is observed with an increase in magnetic field parameter, Jeffreys fluid parameter and Prandtl number. Thermal and concentration buoyancy forces and thermal radiation tend to accelerate the resultant velocity throughout the boundary layer region. The temperature reduces with an increase in Prandtl number and reverse

Ion Slip and Hall Effects on Generalized Time-Dependent Hydromagnetic Couette Flow of Immiscible Micropolar and Dusty Micropolar Fluids with Heat Transfer and Dissipation: A Numerical Study

“…This data represents real MHD generator duct flows and is consistent with relevant publications-see Refs. [35][36][37][38]. The simulation results are verified for the velocity profile by comparing them with the limiting case (the non-MHD, non-dusty, single Newtonian Couette flow for which Ha 2 = 0 Be = 0 Bi = 0 R = 0 1 = 0 2 = 0 r 1 = 1 r 2 = 1Ge = 0).…”

“…PDEs are used in physical modeling, especially in the propagation of sound or heat, electrodynamics, electrostatics, and electricity. Furthermore, in the field of biology and economics, PDEs are available for the description of the complex system; due to this several researchers made multiple investigations [72][73][74][75] of applied sciences with help of PDEs and their solution. Evans et al 76 unfolded the numerical methods for PDEs.…”
