Transmitted and Reflected Coefficients for Horizontal or Vertical Plate Type Breakwater
Abstract：Surface or submerged horizontal or vertical plate can be considered as a new concept breakwater. This paper investigates the wave-plate interaction of this type of breakwater by use of the boundary element method. The relationships of wave transmitted and reflected among plate thickness, submergence and length are carefully studied by numerical simulation. It is shown that: (1) The transmitted coefficients of submerged horizontal plate or vertical plate will become larger with the increase of plate thickness and reduce rapidly with the decrease of plate submergence. (2) Both surface horizontal and vertical plate are efficient for intermediate and short wave elimination, but vertical plate is more effective. (3)Submerged horizontal plate can act more effectively than submerged vertical plate does. With all wave frequencies, the vertical plate almost has no wave elimination effect. 作者： Author： WANG Ke ZHANG Zhi-qiang XU Wang 作者單位： Department of Engineering Mechanics, State Key Laboratory of Structural Analysis for Industrial Equipment, Dalian University of Technology, Dalian 116024, China 期 刊： 中國海洋工程(英文版) ISTICEISCI Journal： CHINA OCEAN ENGINEERING 年，卷(期)： 2011, 25(2) 分類號： P753 Keywords： boundary element method plate type breakwater transmitted reflected 機標分類號： P7 TG1 機標關鍵詞： horizontal plate plate thickness wave boundary element interaction type of short paper use new 基金項目： This work was financially supported by the Scientific Research Foundation for the Returned Overseas Chinese Scholars,Ministry of Education of China，supported by Sciene and Technology Project of Dalian【Transmitted and Reflected Coefficien】相關文章：
