Numerical Modeling of Solitary Wave Interaction with a Submerged Perforated Barrier

In this paper, we investigate the interaction between an isolated solitary wave and an underwater perforated barrier numerically. With the advantages on enhancing water circulations and sediment movements, the perforated barrier is considerably more cost effective and less environmental impact than the conventional hard structures. The numerical results are calculated by a two-dimensional volume of fluid (VOF)-type model which solves the Reynolds-Averaged Navier-Stokes (RANS) equations and the nonlinear k-e turbulence closure model. The main attentions would be paid on tracing the trajectories of fluid particles around the object to help understand possible sediment movements for suspended loads and on evaluating the wave reflection, transmission, and dissipation coefficients using the energy integral method.
