Abstract

This paper studies the boundary layer flow of unsteady incompressible and viscous fluid passing over a porous sphere with forced convection. The non-magnetic viscous fluid was induced by magnetic field of the magnetic porous sphere and it becomes Magnetohydrodynamics (MHD) viscous fluid. The dimensional governing equations are developed from continuity equation, momentum equation, and energy equation. Thus, the governing equations are transformed into boundary layer equations. The boundary layer equations are further converted into non-similar boundary layer and solved numerically by using the Keller-Box method. The outcomes of this research are the effect of magnetic parameter, convection parameter, Prandtl number, porosity parameter, and permeability parameter towards velocity and temperature profiles. When magnetic parameter, convection parameter, and porosity parameter increase and permeability parameter decreases, the velocity profiles increase while the temperature profiles decrease. As an addition, the increment of Prandtl number does not affect the velocity profiles significantly.

N2 - This paper studies the boundary layer flow of unsteady incompressible and viscous fluid passing over a porous sphere with forced convection. The non-magnetic viscous fluid was induced by magnetic field of the magnetic porous sphere and it becomes Magnetohydrodynamics (MHD) viscous fluid. The dimensional governing equations are developed from continuity equation, momentum equation, and energy equation. Thus, the governing equations are transformed into boundary layer equations. The boundary layer equations are further converted into non-similar boundary layer and solved numerically by using the Keller-Box method. The outcomes of this research are the effect of magnetic parameter, convection parameter, Prandtl number, porosity parameter, and permeability parameter towards velocity and temperature profiles. When magnetic parameter, convection parameter, and porosity parameter increase and permeability parameter decreases, the velocity profiles increase while the temperature profiles decrease. As an addition, the increment of Prandtl number does not affect the velocity profiles significantly.
