| Abstract |
The calculated results for the violent impact of water waves onto rigid stationary coastal structures are presented in this paper. The simulation is performed in a numerical wave flume using our recently developed in-house Navier-Stokes solver([4]) named LVOF. It is a VOF finite volume approach that incorporates the surface tension effects, coupled with a dynamic subgrid-scale (SGS) turbulence model. Test cases concern a combination of wave propagation, shoaling, reflection, diffraction, breaking and overtopping after impact. Additionally, the effects of a current on wave-structure interactions are investigated, including the study of the influence of viscosity on the wave boundary layer under breakwater and the 3D effects. Our results demonstrate that our solver can describe most of the significant features of motions induced by regular and irregular waves. In particular, the shape of the free surface agrees well with measurements under grid refinementscaptured and even during lengthy computations. |
