Abstract
In this study, the hydrodynamic performance of a partially submerged vertical slotted barrier was investigated on the basis of an analytical and numerical approach in regular waves. The matched eigenfunction expansion method (MEEM) was used to solve the boundary value problem including the porous boundary condition. Herein the drag coefficient representing the energy dissipation was estimated by the best possible fitting curve to CFD results for a 2D simplified channel model. A 3D implicit unsteady turbulent model based on incompressible Reynolds-averaged Navier–Stokes (RANS) equations was adopted to assess the analytical MEEM solutions. The analytical and numerical solutions show relatively good agreement with the experimental results. The presented analytical and numerical model provides a complementary approach to estimate the hydrodynamic performance and horizontal forces of the vertical slotted barrier effectively and practically.
