Abstract
The simulation of particle settlement in oscillating fluids, which motion is followed by the equation of motion derived by Tchen, is performed, and the results of simulation are verified by the experimental data obtained by Ho. It is revealed that the factors governing retardation of fall velocity are particle Reynolds number, Strouhal number and the ratio of the amplitude of flow oscillation to a particle diameter. Futhermore, when the suspended load in the channel flow is analysed by the simulation model, the criterion of the reasonable calculating time step is proposed based on the results of this study.
