On the movement of a spherical particle in vertically oscillating liquid

The movement of a heavy spherical particle in vertically oscillating liquid is studied by means of an analog computer. Using the Oseen-Tchen-Houghton force-balance model, it is shown that in the case of asymmetrical oscillations the particle may be made quasi-stationary with a finite amplitude of oscillation. It is suggested that under such conditions a mean movement of the particle in the upward direction is also possible.
