A Semi-Infinite Numerical Wave Flume Using Smoothed Particle Hydrodynamics
نویسندگان
چکیده
This paper presents the new boundary condition implemented in the LNEC (Laboratório Nacional de Engenharia Civil) SPH (Smoothed Particle Hydrodynamics) numerical model based on the SPHysics model and on a standard SPH formulation: This piston-type wave-maker now includes dynamic wave absorption and allows the simulation of 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.

The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH). In the current ISPH method, the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free ve...

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
