Influence of a magnetic field on the flow of a micropolar fluid sandwiched between two Newtonian fluid layers through a porous medium

Abstract: The present problem is concerned with the flow of micropolar/Eringen fluid sandwiched between two Newtonian fluid layers through the horizontal porous channel. The flow in both the regions is steady, incompressible and the fluids are immiscible. The flow is driven by a constant pressure gradient and a magnetic field of uniform strength is being applied in the direction perpendicular to the flow. The flow of electrically conducting fluids, in the three regions, is governed by the Brinkman equation with the assu… Show more

“…Moreover, the volumetric flow rate was calculated, while the microrotation parameter, geometric parameter and Hartmann number effects on the flow were investigated. Yadav et al [19] studied the flow of a micropolar fluid between two Newtonian fluid layers through a horizontal porous channel. The flow was driven by a constant pressure gradient and a uniform magnetic field was applied in the direction perpendicular to the flow.…”
