Water Wave Interaction by Dual Cylindrical Caisson Breakwater with Partial Porous Area

In order to design a reliable breakwater that will withstand severe environmental conditions, accurate prediction of hydrodynamic interactions with multi-bodied structures must be considered. However, the interaction processes among dual cylindrical caisson breakwaters, which consist of a partial porous outer cylinder and an impermeable inner cylinder, are very complex and numerous. In the present study, the 3D numerical analysis method is developed with eigenfunction expansion method to evaluate the water wave interaction. The wave forces on the array of dual cylindrical caisson breakwaters with partial porous area are presented for various conditions.
