Implicit Scheme for Micropolar Magnetohydrodynamic Fluid Flow through a Magnetic Porous Sphere

This paper considers the effect of both mixed convection and magnetic fields on unsteady micropolar fluid that flow through a magnetic porous sphere. We develop the dimensional system of equations obtained from continuity, momentum, and energy equations. We further transform those dimensional equations into non-dimensional equation by introducing non-dimensional variables. We use boundary layer i.e, theory by using stream function, to obtain similarity function. Those similarity functions are further solved numerically by using Implicit Scheme. We obtain that when magnetic parameters increase and velocity profile increases. When the magnetic parameters increase then microrotation profile decreases.
