Abstract

<p>We investigate lateral migration of particles dispersed in Stokes fluid. Arbitrary shaped and non-uniform charge distributed particles are discussed in this paper. Translation-rotation coupling of the particle sometimes produces the complex motions. The motions of the particles are not always parallel to external fields, such as gravity, electric field and shear flow. The migration direction and the trajectories of the particles are dependent on their shapes etc. Especially chiral particles, which cannot be superimposed to their mirror images, migrate to opposite direction of their mirror images isomer. The topics here can be applied to the separation method of the particles.</p>
