Performance Evaluation of the Submerged Dual Buoy/Porous-membrane Breakwaters in Oblique Seas Conference Paper uri icon


  • The present paper outlines the numerical investigation of obliquely incident wave interactions with fully submerged and floating dual buoy/vertical-porous-membrane breakwaters. To assess the efficiency of this dual porous system, two-dimensional multi-domain hydro-elastic formulation was carried out in the context of linear wave-body interaction theory and Darcy's law. If the breakwater system is properly tuned for mutual cancellation to the coming waves, it has high performances in reflecting the obliquely incident waves over a wide range of wave frequency and headings. Permeability on membranes significantly reduces large motions of buoy and membranes at resonance frequencies by energy dissipations through fine pores.
