A Semi-Infinite Numerical Wave Flume using Smoothed Particle Hydrodynamics
| Summary: | This paper presents the new boundary condition implemented in the LNEC SPH numerical model based on the SPHysics model and on a standard Smoothed Particle Hydrodynamic formulation: the piston-type wave maker includes now dynamic wave absorption and allows simulating a semi-infinite flume. Verification of the active wave maker absorption is carried out through the simulation of the interaction between a regular incident wave and an impermeable vertical breakwater. Results show that the active wave-maker allows outgoing waves to be absorbed and reflection at the wave-maker to be avoided |
