Abstract—In the present study, the 3D numerical analysis method is developed with Eigenfunction expansion method to evaluate the wave forces acting on the array of dual cylindrical cylinders with partial porous area, which consist of an impermeable inner cylinder and a porous outer cylinder. The wave forces and water wave interaction on dual cylindrical cylinders with partial porous area are presented for various porosity depths, and the comparison between the impermeable cylinder and the permeable cylinder is made to examine the effects of porosity. From these results, the present method is very useful to evaluate the wave force and water wave interaction acting on the array of dual cylindrical cylinders with partial porous area.
