Abstract

A three-dimensional numerical study has been undertaken to investigate the interactions of solitary waves and a horizontal plate. Both cases of suspended and submerged rigid plates in water are considered. The large-eddy simulation approach has been adopted in this study, where the model is based on the filtered Navier-Stokes equations with the dynamic Smagorinsky sub-grid model being used for the unresolved scales of turbulence. The governing equations have been discretized using the finite volume method, with the air-water interface being captured using a volume of fluid method and the cut cell method being implemented to deal with complex geometry in the Cartesian grid. Numerical results have been presented the free-surface elevations and pressure on the horizontal plate. Detailed free surface profile, velocity fields and vortical structures in the vicinity of the plate are shown and discussed.
