Based on the fluid volume fraction large eddy simulation discrete phase coupling model, water and sediment flow around vibrating monopile was simulated. The momentum model enhanced using force distribution of particle bed surface. Additionally, dynamics incipience a replicated through use Shields number. results suggest that vibrations amplify negative in both front deceleration region wake reflux region. Furthermore, within periodic field surrounding monopile, temporal changes number does not consistently match spatial average velocity.
