Abstract
We consider unsteady micropolar fluid flow pasta sliced sphere. We further develop
dimensional governing equations. These equations are obtained from conservation of mass and
conservation of momentum equations. We further convert the dimensional governing equations into
non-dimensional equations by using non-dimensional variables. Further, the non-dimensional equations
are reduced to become non-linear differential equation. The non-linear differential equations are solved
by using finite difference method with Keller-box scheme. Numerical results show that the
characteristic of unsteady micro-polar fluid on boundary layer flow past a sliced sphere for the velocity
profile increases in strong and weak concentrations. When a sliced angle value increases then the
velocity profile will increase. The micro-rotation profile increases in strong concentration. However,
when the sliced angle increases then the micro-rotation profile will decrease. The micro-rotation profile
decreases in weak concentrations. However, then the micro-rotation profile will increase when the
sliced angle increases.
