Magnetohydrodynamics with Forced Convection in Micropolar Fluid Flows Pass a Magnetic Porous Sphere

The research of fluid flows is growing. The physical research requires a high cost. So, it is needed science studies that can solve the problem. One of them is mathematical modeling. This research considers magnetic field effect in unsteady magnetohydrodynamics of micropolar fluid through a magnetic porous sphere with forced convection. Governing equations are derived from continuity, momentum, angular momentum, and energy equations. The form of these equations are two dimensional partial differential equations. Dimensional equations are transformed to non-dimensional equations and then, it will be converted to similarity equations. The similarity equations are solved numerically using Keller-Box scheme. It could be concluded that velocity curve decreases when magnetic, porosity and micropolar parameters increase. Microrotation curve increases with the increasing of magnetic, porosity, and micropolar parameters.
