摘要

The interactions between a solitary wave and a submerged, vertical, fixed slotted barrier are investigated numerically. Two various locations of slotted barrier are considered by varying the vertical distance from the structure to the free surface and the floor. Numerical results are calculated by a well-validated two-dimensional volume of fluid (VOF) type model, named COBRAS (COrnell BReaking And Structure), based on the Reynolds-Averaged Navier-Stokes (RANS) equations and the k-e turbulence closure solver. In particular, the active wave absorption inflow boundary is incorporated to avoid re-reflection and reduce the computational cost. Experiments had been conducted to measure the free surface motion as a means of model calibration for the case of impermeable barrier. Fairly good agreements at both pre-and post-breaking stages are observed. Then, the numerical results are employed to illustrate the vortex shedding in details for different porosities and locations of the target structure.
