long crested Wave generation and absorption for sph based dualsphysics model
Coastal Engineering, 2017Co-Authors: Corrado Altomare, J M Dominguez, A J C Crespo, Jose Gonzalezcao, Tomohiro Suzuki, M Gomezgesteira, Peter TrochAbstract:Abstract The present work presents a fully comprehensive implementation of Wave generation and active Wave absorption for second-order Long-Crested monochromatic and random Waves in a WCSPH-based (Weakly Compressible Smoothed Particle Hydrodynamics) model. The open-source code DualSPHysics is used for the scope. The numerical flume resembles a physical Wave facility, so that, the moving boundaries mimic the action of a piston-type Wavemaker. The second-order Wave generation system, capable of generating both monochromatic (regular) and random (irregular) Waves, is implemented jointly with passive and active Wave absorption. A damping system is defined as solution for passive absorption and is used to prevent Wave reflection from fixed boundaries in the numerical flume. The use of active Wave absorption allows avoiding spurious reflection from the Wavemaker. These implementations are validated with theoretical solutions and experimental results, in terms of water surface elevation, Wave orbital velocities, Wave forces and capacity for damping the re-reflection inside the fluid domain.

prediction formula for the spectral Wave period t m 1 0 on mildly sloping shallow foreshores
Coastal Engineering, 2017Co-Authors: Bas Hofland, Corrado Altomare, Xuexue Chen, P OosterloAbstract:During the last decades, the spectral Wave period Tm-1,0 has become accepted as a characteristic Wave period when describing the hydraulic attack on coastal structures, especially over shallow foreshores. In this study, we derive an empirical prediction formula for Tm-1,0 on shallow to extremely shallow foreshores with a mild slope. The formula was determined based on flume tests and numerical calculations, mainly for straight linear foreshore slopes. It is shown that the Wave period increases drastically when the water depth decreases; up to eight times the offshore value. The bed slope angle influences the Wave period slightly. For short-crested Wave fields, the strong increase of Tm-1,0 starts closer to shore (at smaller water depths) than for Long-Crested Wave fields.
