A new particle interaction method for fluid-solid particles

The ocean waves and broken waves can disturbance the sea bed at the near shore. Its disturbance can be calculated by measuring or estimating of wave loads, and then apply the obtained load on the sea bed model. At this time, it has two step, firstly the it needs to calculate wave loads from computational fluid dynamics technique, and the sea bed model as soil are fed this load to calculate the soil movement. In this study, the particle method based on the Lagrangian approach is employed to simulate the wave load estimation and the soil movement simultaneously. The particle method has two forms which are fluid particle model and solid particle model, and two models are dynamically interacted to solve the soil disturbance problem.
