Abstract
- Based on the wave radiation and diffraction theory, this paper investigates a new type breakwater with upper arc-shaped plate by using the boundary element method (BEM). By comparing with other three designs of plate type breakwater (lower arc-shaped plate, single horizontal plate and double horizontal plate), this new type breakwater has been proved more effective. The wave exiting force, transmission and reflection coefficients are analyzed and discussed. In order to reveal the wave elimination mechanism of this type of breakwater, the velocity field around the breakwater is obtained. It is shown that: (1) The sway exciting force is minimal. (2) When the ratio of the submergence and wave amplitude is 0.05, the wave elimination effect will increase by 50% compared with other three types of breakwater. (3) The obvious backflow is found above the plate in the velocity field analysis. [ABSTRACT FROM AUTHOR]
