THE LIFT GENERATED BY VIBRATIONAL MOTIONS

By applying the reacted pressure on the “deformed” surface, we have calculated theoretically the time-averaged lift forces exerted on a vibrating body in the fluid medium with the non-viscosity and small disturbance assumptions. The lift turns out to be proportional to the product of the amplitudes of translating and deforming vibrations. We could thus deduce the scaling law applicable for the forces generated by the vibrational motions in the fluid medium.
