THREE-DIMENSIONAL NUMERICAL SIMULATION OF WAVE SLAMMING ON AN OPEN STRUCTURE

The three-dimensional numerical simulation of wave slamming on an open structure in the splash zone is carried out based upon the Volume Of Fluid (VOF) method. A wave basin is established by solving the continuity equation and the Navier-Stoke equations. The linear wave-maker is placed on the left side of the basin, and the numerical sponge layer and the SRC are placed on the right side of the basin to damp the incident waves. The three-dimensional wave slamming boundary condition is adopted to model waves in contact with and separated from the underside of the structure. The numerical results of wave slamming on a foursquare structure for various parametric cases are verified by the experimental results. Meanwhile, the characteristics of the wave impact forces on the undersides of the rectangular structures with various length-breadth ratios are discussed.
