The movement of nano/micro-particles in a viscous media has
recently received attention due to its diverse applications in applied science
and engineering. In the current chapter, the interactions of a two-solid
microspheres system in Stokes ow at low Reynolds number power by an external
oscillator field is studied analytically. A conducting microsphere moves under
the action of an external field, and the other nonconducting sphere moves due
to the induced ow oscillation generated by the motion of the active sphere. The
governing equation in the vector form for the two-sphere system is formulated
and solved asymptotically using the two-timing method. For illustrations, by
applying a simple oscillatory external FIeld, the results show that no
collisions occur between two spheres as the system moves in a circular motion
with a fixed separation distance, and that its trajectory was found to be
inversely proportional to the frequency of the external field.
