FALLING SEDIMENT PARTICLES UNDER PROGRESSIVE WAVE

Coastal areas are a typical example of multi-phase environment, which sediments and marine waters interact another during time. Herein, a two-phase numerical lagrangian model using MPS method is developed which precisely simulate sediment particles motion in flow domains. The developed two-phase model is applied in a calm water tank and sediment falling is studied. Calculated results are in accordance with experimental data and the ability of developed model in sediment motion prediction is approved. In the next step, the developed model is applies in a wave flume and sediment motion under progressive wave is predicted.
