Summary
The force experienced by a rigid particle in the Stokes flow of micropolar fluid is investigated. In the case where the particle is translating, it is shown that this force is a functional of the free-stream velocity. An integral expression is obtained for the force when the particle is immersed in a flow field which tends to an arbitrary Stokes field at infinity. The corresponding Faxen's law for micropolar fluids is then deduced. Finally, multiparticle systems are examined.
