Abstract

Abstract: In this paper, based on linear potential flow theory, an alternative semi-analytical model is developed using the potential decomposition method for wave interaction with a vertical cylinder with a submerged porous plate. The semi-analytical model is verified by comparing with the previous analytical results and the numerical results. The influence of geometrical/physical parameters is further investigated. Results show that there exists a critical frequency beyond which the wave loads on the vertical cylinder are mitigated significantly. The submergence and the radius of the porous plate are the key factors affect the wave loads on the cylinder. Highlights: An alternative semi-analytical solution is developed for a vertical cylinder with a submerged horizontal porous plate. A critical frequency k c, beyond which the wave loads can be mitigated significantly, was observed theoretically. Further analysis on the wave interaction with a vertical cylinder with a submerged plate is conducted.
