在存在位于水下结构背风侧的垂直墙的情况下，研究了水下结构和垂直台阶引起的水波散射。本征函数展开方法用于推导以无限傅里叶级数明确表示的速度势。傅立叶级数中出现的未知数是通过求解线性方程组来计算的，线性方程组是通过使用两个界面处的速度和压力的连续性条件获得的。对于不同的几何参数，计算了作用在水下主体和垂直壁上的波浪引起的水动力。
Water wave scattering by a submerged structure and a vertical step is studied in the presence of a vertical wall which is placed in the lee side of the submerged structure. The eigenfunction expansion method is used to derive the velocity potential which is presented explicitly in terms of infinite Fourier series. The unknowns appear in the Fourier series are computed by solving a system of liner equations which are obtained by using the conditions of continuity of velocity and pressure at two interfaces. The wave induced hydrodynamic forces acting on the submerged body and vertical wall are computed for different geometrical parameters.
