Numerical analysis on wave load reduction effect of a solid wall with porous plate by macroscopic CFD approach

The porous structures are widely designed in coastal and ocean engineering to reduce the wave load. A macroscopic CFD approach is established study interaction with a plate placed front of solid wall. numerical tank was firstly validated by analytical results vertical wall, model experimental single plate. Then load reduction effect wall investigated, influences porosity relative gap width compared, effects height also analyzed. demonstrate that main factors force effect, forces on structure increase almost linearly height, while coefficient refection not linearly. 0.2 0.2–0.3 deemed be optimal geometry parameters at which optimal. total horizontal increases nonlinearly heights, quadratic pressure drop condition essential when studying thin structures.
