Flow of Immiscible Micropolar Fluids Between Two Porous Beds

The article deals with the flow of two immiscible incompressible micropolar fluids between two homogeneous porous beds at the bottom and top when the beds are of (A) infinite thickness and (B) finite thickness. The flow of two immiscible micropolar fluids is considered in two zones (zone II and zone III). This flow is bounded by zone I at the bottom and zone IV at the top, with saturated porous beds. In case A, zones I and IV are of infinite thickness with low permeability saturated by viscous fluids with the flow modeled by Darcy's law. In case B, zones I and IV are of finite thickness with high permeability saturated by viscous fluids with the flow modeled by Brinkman's law. The effects of the physical parameters on the velocity and microrotation vector are investigated.
