Numerical Simulation on Solitary Wave Propagation and Run-up by SPH Method

Smoothed Particle Hydrodynamics (SPH) is a meshless method which takes a Lagrangian approach. It is different from the traditional methods using mesh system. A number of numerical simulations of a solitary wave propagation using SPH method on a vertical wall and a sloping wall are carried out. The wave run-ups obtained this simulations are compared with the experimental date and resulted good agreement. The water surface profile on a sloping wall is also compared in detail with the experimental data and a good agreement is obtained. The results of particle configuration and velocity distribution at various times are visualized. It is shown that the method can simulate the sloshing phenomena of a solitary wave propagation, run-up, run-down and backwash with good accuracy.
