摘    要:采用解析方法研究了斜向入射波作用下双淹没矩形体的透反射系数特性.首先利用特征函数展开法导出了绕射势函数的分析解并进一步得到透反射系数的计算公式,然后利用边界元方法验证了解析解.与单个的淹没矩形体相比,双淹没矩形体在一定范围内有较高的反射系数.最后利用解析解分析了若干工况下的双淹没矩形体的透反射特性,给出了影响透反射系数的几何因素.

关 键 词:绕射势    反射系数    透射系数    双淹没矩形体

Abstract:An analytic method is used to analyze the transmission and reflection coefficients of double-submerged rectangular blocks(DSRB) in oblique waves.The diffraction potential functions are obtained by(using) the eigenfunction expansion method,and expressions for reflection and transmission coefficients are defined.The boundary element method is used to verify the correctness of the present analytic method.The DSRBs have better performance than single submerged rectangular blocks in some certain cases.The reflection and transmission properties of the DSRBs are studied for some specific cases,and the influence of geometrical parameters is also presented.
Keywords:diffraction potential  reflection coefficients  transmission coefficients  double-submerged rectangular block
