abstract

The application of smoothed particle hydrodynamics (SPH) to model the three-dimensional fluid-structure interaction for waves approaching a rigid mound breakwater is presented. The main purpose is to examine the influence of the forms of block sea breakwater on its overtopping. The problem includes extremely large deformations of the free surface fluid. To better understand such deformations, a three-dimensional SPH code is applied to analyze the dynamic responses of fluid-rigid structure interaction. In the classical SPH formulation, the Navier-Stokes equations are solved and the fluid is treated as weakly compressible. The numerical model is first validated against experimental data for two-dimensional and three-dimensional breakwater problems, it shows a fair agreement of overall fluid motions. The open-source GPU code, DualSPHysics, enables the simulation of millions of particles required for the accurate simulation of the run-up on a rigid structure. SPH has been proven to be a suitable method for practical applications in marine engineering. The aim is to investigate the reliability of this approach as a design tool.
