Velocity profiles at non-stagnation point of viscous fluid passes a sliced sphere contains magnet

Abstract

Abstract This paper will be presented to explain the velocity profile of viscous fluids at non-stagnation points when the fluid passes through a sliced sphere contains magnet. The design of this study was an experiment using computer simulations based on mathematical models built. Mathematical models and coordinate systems are built based on physical phenomena and are composed of continuity equations and momentum equations. The model was converted to a non-dimensional model and solved by the Keller Box numerical method. Numerical simulations are carried out by varying the incision angle and looking at the fluid velocity profile that occurs. The simulation results show that if magnetic parameter is not included then the velocity will be different at each point, the greater the observation angle the greater the velocity. If magnetic parameter is included then the velocity will tend to be the same. If an observation angle hold on any value then the greater the magnetic parameter the greater the velocity.
