Abstract

The strongly nonlinear interaction between a solitary wave and the submerged barrier is investigated numerically in the present paper. Based on the Cartesian grid method of constrained interpolation profile (CIP), a two-dimensional numerical wave flume specializing to Navies-Stokes equations was established to simulate the propagation of a solitary wave over the submerged structure. The free-surface motion and hydrodynamic forces acting on the submerged breakwater were presented in this work. The comparisons between the numerical results and experimental data for the free surface elevations show a good agreement in both upstream and downstream of barrier. Complicated hydrodynamic behaviors, including wave breaking and overtopping, were captured by the numerical model which demonstrates that the CIP-based model has the ability to provide the reliable predictions for the wave transmission over the submerged structure.
