Description
Summary:The time-dependent flow of two immiscible fluids through the channel having porous regions driven by electric and magnetic fields has been investigated. The proposed model was segregated into two regions: the lower region contains Casson fluid and the upper region has a Newtonian fluid. The continuity of velocities and shear stresses were developed at the interface region. The analytical solution was carried on the momentum equations under the pressure and electromagnetic forces. The variation of velocity profiles and wall shear stress has been studied under various physical conditions and produced in graphical form. We found that when the Casson parameter approaches infinity and the viscosity ratio assign the value of unity, the fluids present in both regions behave as Newtonian fluids. It is observed that Magnetic parameters, electric force and viscosity ratio become controlling parameters to regulate the flow in the channel based on the anticipated physical conditions of problems.
