Hall effects on hydromagnetic flow of an Oldroyd 6-constant fluid between concentric cylinders

Hall effects for MHD Oldroyd 6‐constant fluid flows using finite element method

“…Unlike the flow analysis of Reference [20] Equation (4) does not correspond to the hydrodynamic case when m →∞. Numerical simulation here is also achieved through finite element method.…”

“…In view of their importance, several authors [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] have recently studied non-Newtonian fluids in various situations. Very recently, Rana et al [20] analyzed the magnetohydrodynamic (MHD) flows of an Oldroyd 6-constant fluid between two concentric cylinders. In fact, the conclusion that m →∞ gives the result of the hydrodynamic case is not correct.…”

“…In fact, the conclusion that m →∞ gives the result of the hydrodynamic case is not correct. This happens due to a mistake in Equations (9), (12), (21), and (23) of Reference [20]. They discussed the Poiseuille and generalized Couette flows using finite difference scheme.…”

Numerical treatment and Global Error Estimation of a MHD Flows of an Oldroyd 6-Constant Nano-Fluid through a non-Darcy Porous medium with Heat and Mass Transfer

“…Hayat et al [24] studied the effect of the slip condition on flows of an Oldroyd 6-constant fluid. Rana et al [14] studied the Hall effects on hydromagnetic flow of an Oldroyd 6-constant fluid between concentric cylinders by the finite difference method. Hayat et al [26] investigated the exact solution of a thin film flow of an Oldroyd 6-constant fluid over a moving belt by the Homotopy perturbation.…”

Magnetohydrodynamic Rotating Flow of a Fourth Grade Fluid Between Two Parallel Infinite Plates

“…A complete and thorough discussion of various models can be found in [4][5][6][7]. Various authors [8][9][10][11][12] investigated non-Newtonian fluids.…”
