| Abstract | In this study, the breaking wave forces on a jacket (steel space frame) structure are simulated using a 3D numerical model. The model is based on solving the viscous and incompressible Navier-Stokes equations for a two-phase flow (air and water) model and the volume of fluid method (VOF) for treating the free surface of the water. A cut-cell method is used to install the complicated geometry (e.g., jacket structure) in the computational domain. The numerical model is validated by using experimental data obtained at the Large Wave Channel (GWK), Hannover, Germany. Free surface elevation, water particle velocities and total forces on the structure were calculated with the numerical model, for both breaking and non-breaking cases and are compared with the experimental data. The simulation results show good agreement with the experimental data. Based on the validated numerical results, slamming coefficients on the front and back vertical members are estimated. In addition to this, the reasons why maximum values of breaking wave forces measured in the total time series show a large degree of scatter are briefly discussed. |
