Stokes flow of an incompressible micropolar fluid past an approximate sphere. (English) Zbl 0760.76001

Summary: The paper concerns the flow of an incompressible micropolar fluid past an approximate sphere, assuming uniform stream far away from the body along its axis of symmetry. The velocities are expressed in terms of a stream function and expressions for velocities and microrotation component are derived. The drag experienced by the approximate sphere is evaluated and its variation is studied with respect to the material parameters. The flows past a sphere and an oblate spheroid can be obtained from the present analysis as special cases.
