Wave Scattering and Radiation by a Dual Porous-wall Attached Floating Body System

摘要

In the present study, an analytical solution of a sinusoidal wave propagating through a dual porous-wall attached floating body system is presented with application of the two-dimensional linear potential theory. Two sets of orthogonal Eigen functions are utilized to determine the velocity potential and associated unknown coefficients in each subdomain. The reflection coefficients and transmission coefficients as well as the net hydrodynamic force along surge, heave and pitch are also formulated. The results show that the wave reflection and transmission effects are depended heavily on the relative water depth and the porous properties. Aso, it can be found that the porous properties play an important role for the pitch forces acting on this system, however, the influences on the surge and heave forces are less important.
