A basic question on sediment suspension in nature fluid body is why the sediment particles do not settle down even though they are heavier than the surrounding fluid. Among the different plausible suggestions, one possible explanation is that flow oscillation provides a mechanism to keep the sediment particle in suspension. An analytic-numeric study has been carried out to investigate the settling behavior of a rigid homogeneous sphere in a vertically oscillating fluid, particularly to identify the oscillation-induced levitation condition at which a particle responds to the vertically oscillating fluid so that the net gravity force is completely neutralized and the particle merely oscillates about a fixed level. Applicability of the analytic-numeric study is tested by using experimental data obtained in the present research as well as by other previous researches.
