要約

The steady axisymmetric uniform flow of an incompressible micropolar fluid past a porous sphere embedded in another porous medium has been studied analytically. The stream function solution for both the inner and outer flow field is acquired by using the Brinkman equation. Explicit expressions are determined for both the flow fields by taking the appropriate boundary conditions across the surface of the porous sphere. Furthermore, the non-dimensional drag experienced by a porous sphere embedded in another porous medium of micropolar fluid is calculated. Effects of drag force and shearing stress on permeability parameter, the viscosity ratio for the porous sphere is presented graphically and numerically. Some special cases of flow past a porous sphere have been validated with earlier well-known cases.
