MHD flow of a micropolar fluid over a stretchable disk in a porous medium with heat and mass transfer

Abstract

This article studies the simultaneous impacts of heat and mass transfer of an incompressible electrically conducting micropolar fluid generated by the stretchable disk in presence of porous medium. The thermal radiation effect is accounted via Rosseland’s approximation. The governing boundary layer equations are reduced into dimensionless form by employing the suitable similarity transformations. A finite difference base algorithm is utilized to obtain the solution expressions. The impacts of physical parameters on dimensionless axial velocity, radial velocity, micro-rotation, temperature and concentrations profiles are presented and examined carefully. Numerical computation is performed to compute shear stress, couple stress, heat and mass rate at the disk.

MHD thermally radiative flow of Carreau fluid subjected to the stretching sheet by considering non-Darcy Forchheimer law

“…Ashraf and Bashir [19] discussed the impacts of heat transfer on hydromagnetic stagnation point flow of micro polar liquid through a shrinking sheet. The influence of heat and mass transfer on MHD flow of a non-Newtonian (micropolar) liquid over a disk was examined by Rauf et al [20]. The problem of hydromagnetic flow of micronanoliquid owing to shrinking sheet was solved numerically by Rauf et al [21].…”
