Unsteady magnetohydrodynamics of viscous fluid past a magnetic sliced sphere

Magnetohydrodynamics (MHD) is important study in engineering and industrial fields. Power generators and magneto-hidrodynamic accelerators, nuclear reactor coolants and crystal growth are the development of this MHD field. The study of MHD that past a magnetic sliced sphere is an interesting thing to learn more. This paper considers the unsteady viscous fluid MHD that flowing past a magnetic sliced sphere under the influence of mixed convection. We construct mathematical model of MHD flow in viscous fluid to obtain dimensional governing equations. Then, the equations converted into non-dimensional equations by using non-dimensional variables and unsimilarity equations using stream function. The solution of the model solved by numerically using the Keller-Box scheme. The various non-dimensional parameters such as Prandtl number, sliced angle, magnetic parameters, and mixed convection parameters use to obtain the velocity and temperature profiles. We obtain that when magnetic parameter increases then fluid velocity decreases but fluid temperature increases. For the convection parameter increases then the velocity of the fluid increases but the temperature of the fluid decreases. For the Prandtl number parameter increases then both of the velocity and temperature of the fluid decrease. For the sliced angle parameter increases then the fluid velocity increases but the fluid temperature decreases.
