摘要
针对计算域中存在直立岛式结构物的复连通区域,基于时间关联型缓坡方程和相应的边界条件,建立了在计算域中存在直立岛式结构物时波浪传播的数值模拟模型。该模型不仅适用于变水深问题,而且适用于模拟线性波浪的时间和空间演化过程。对直立岛式防波堤及直立方柱周围波浪传播变形的数值模拟表明,所建立的模型能够有效地模拟计算域内存在直立岛式结构物的波浪绕射和反射问题。
For the purpose of studying wave propagation in the water area with vertical structures, a numerical wave model in the multiply connected domain is developed based on the mild-slope equation and the corresponding boundary conditions. This model could not only be applied to the case of varying topography, but also be used to simulate the linear wave evolution both in time and space. Tests are made for wave transformation near an island breakwater and wave transformation near a rectangular cylinder, and the results illustrate that the present model could be applied to simulate wave reflection and refraction in water area with vertical island structure.
