Wave impact on a vertical wall has been investigated in a physical and numerical wave tank. Two different impact phenomena were explored. A flip-through, where the front face of the wave was moving rapidly vert
The two methods are used to simulate solitary wave propagation in water of uniform depth, followed by a wave impact on a vertical wall. The simulations focus on the determination of the maximum run-up of the wave on the wall, the calculation of pressures exerted by water on the structure,...
Due to the existence of the outer porous cylinder, both hydrodynamic force acting on the interior cylinder and wave amplitude around the windward side of the interior cylinder are reduced if compared with the results by a direct wave impact without an outer porous cylinder. Regarding the porous ...
Multidisciplinary knowledge focuses on traditional academic disciplines, like ecology, law, economics, governance, ethics and sociology. It emphasises T-shaped knowledge, where a deep understanding of a narrower sub-discipline (the vertical line of the T) is married to a more general appreciation of ...

In contrast with the general wave overtopping characteristics of periodic waves, the maximum overtopping water surface elevation in front of the vertical wall is higher in a VR than in a WAR. However, the order of maximum inundation heights reverses as the wave propagates inland. Keywords: ...
This counter-intuitive dynamic mechanism can be used to create a highly efficient--yet reusable--impact mitigating system without relying on material damping, plasticity or fracture. 展开 关键词: Nonlinear Sciences - Pattern Formation and Solitons ...

Wave impact on a vertical wall has been investigated in a physical and numerical wave tank. Two different impact phenomena were explored. A flip-through, where the front face of the wave was moving rapidly vertical due to a jet and a case with a very steep wave were generated in a wave...
Wave transformation is computed for a variety of scenarios using the OpenFOAM variant IHFOAM. In agreement with previous studies, the largest pressures and loads occur when there is a violent impact with near-breaking or just-broken waves on the wall, causing a strong vertical jet. This ...
