Abstract: Based on SPH method, a mathematical model was established to simulate the interaction between nonlinear waves and structures.
The calculation method of particle pressure at the boundary is improved, and the problem of pressure oscillation near the boundary of free surface and solid wall is solved.
The boundary conditions of non-reflective wave-building, periodic side boundary conditions and artificial viscous wave-eliminating boundary conditions suitable for SPH method are proposed, and the periodic wave numerical flume/pool based on SPH method is established.
The mathematical model is used to simulate the interaction between wave and floating body, the propagation and deformation process of wave in permeable structure, and the stability of discrete protective block under wave action.
