Numerical simulation with a macroscopic CFD method and experimental analysis of wave interaction with fixed porous cylinder structures

Porous structures have been widely applied in the coastal and ocean engineering due to their wave energy dissipation mechanism. The macroscopic computational fluid dynamics (CFD) approach where quadratic pressure drop condition of porous surface is introduced model interaction with cylinders. A series CFD simulations waves interacting a single cylinder combined structure concentric inner solid column are performed, corresponding tank tests conducted. method compared experiments, linear potential model, BEM (boundary element method) model. effects porosity radius on force heights inside analyzed evaluate performance shell reducing loads elevation, variation incident amplitudes also investigated. results demonstrate that established reliable for analysis thereby being great significance reference purpose structures.
