Abstract

The kernel function and the surface particle tracking method is very important for Smoothed-particle hydrodynamics (SPH) model. A new kernel function and surface particle tracking method are introduced in SPH model in this paper, and the optimized SPH model is verified by experimental data. Then the optimized model is used in simulating the interaction between wave and semi-circular breakwater to calculate the transmission and reflection coefficient, and in the interaction between structure and tsunami is as well studied by using the 3D SPH model.
