Uniform Flow of Viscous Fluid Past a Porous Sphere Saturated with Micro Polar Fluid

Abstract

The analytical investigation of a uniform flow of a viscous fluid past a spherical ball filled with porous medium saturated by Micropolar fluid is considered. Velocity function is defined in the form of stream function. The flowing shape is obtained for the outer and inner regions of the sphere. The effects of physical parameters like porosity and micro polarity parameters on the flow and on the drag on the sphere are shown in graphs. It is observed that when the porosity parameter is between 0.05 to 0.2, we find another concentric fluid sphere enclosing the porous sphere. Below and above this range, the fluid sphere disappears.
