Wave Interactions with a Porous and Flexible Cylindrical Fish Cage

The hydrodynamic response of a porous flexible circular-cylinder in regular waves was analytically studied. To simplify the problem, the bottom of the cylinder was considered as rigid porous plates. Small amplitude water wave theory and structural responses were assumed. The velocity potentials were solved using the Fourier-Bessel series expansion method and the least squares approximation method. The present study represents a preliminary step in the study of the fish cage.
