| 英文摘要 | In complex ocean dynamics environment, the mechanism revelation of dynamic responding and stability assessment of marine structures built on seafloors are key scientific and technological issues in the field of ocean engineering. Some coupled models for wave-structure interaction have been developed employing Navier-Stokes solvers based on the finite volume method (FVM), i.e., OpenFOAM in previous studies. However, these grid- based CFD methods were not good at handling the breaking of extreme waves, and their computational scale was frequently limited, as well as the mesh generation process was relatively complex. In this study, a NavierStokes solver based on the Smoothed Particle Hydrodynamics (SPH) method from the Lagrangian perspective is utilized to simulate the complex wave motions, and the FEA software FssiCAS and the SPH solver DualSPHysics are integrated together through the way of data exchange at solid-fluid interfaces. Then a one-way coupling numerical model for fluid-structure-seabed interaction is established. The reliability of the developed one-way coupling model is validated adopting a typical analytical solution and several wave flume tests. Finally, the developed one-way coupling model is applied to explore the dynamic responses, and evaluate the stability of the revetement breakwater built on reclaimed coral sand foundation in the South China Sea. It is indicated that the developed one-way coupling model FssiCAS-DualSPHysics exhibits a high reliability and provides an effective analysis tool for the dynamic response and stability evaluation of large-scale marine structures in practical engineering. |
